fs/iso9660: really create initrd temp dir

In case we're using an initrd, we create an empty "root" directory that
will contain only the bootloader stuff, not the actual root filesystem,
because it is in an initrd (standalone or initramfs).

We have to ensure that the directory is empty before assembling the
filesystem (to avoid any file lingering from a previous run, like the
sequence  "make; make"). So we first remove it before we create it, so
that on each build (especially not-from-scratch builds) we get the exact
expected content without any leftover.

However, the macro responsible for that, although defined since 7080eef9,
was never called.

Fix that by registering it as a pre-gen hook.

Note: the directory need not be created, as there are quite a few
"install -D" commands that ensure it is created. Yet, we prefer to
create it explicitly to avoid any confusion.

elf2flt: add patch to fix ld.real search logic

elf2flt contains a program called ld-elf2flt, which gets installed as
a replacement for ld, with ld renamed to ld.real. This program
therefore calls ld.real internally.

The logic to find ld.real worked fine for:

 - bin/TARGET_ALIAS-ld
 - TARGET_ALIAS/bin/ld

However, it failed badly if bin/SIMPLER_TARGET_ALIAS-ld is used, as
symlink to bin/TARGET_ALIAS-ld. For example:

$ ./output/host/bin/arm-buildroot-uclinux-uclibcgnueabi-ld
/home/thomas/buildroot/buildroot/output/host/bin/../arm-buildroot-uclinux-uclibcgnueabi/bin/ld.real: no input files

arm-linux-ld (ld-elf2flt): error trying to exec '/home/thomas/buildroot/buildroot/output/host/bin/ld.real': execvp: No such file or directory

/home/thomas/buildroot/buildroot/output/host/arm-buildroot-uclinux-uclibcgnueabi/bin/ld.real: no input files

This reverts commit c69088b8c35177cecdd0f1f385c13f5b2c509f1d, which is
no longer needed now that alsa-lib has been fixed properly.

Indeed, this commit was made because alsa-utils failed to build with:

collect2: error: ld returned 1 exit status

Which is exactly the problem that we fixed in alsa-lib by making sure
that rawmidi_symbols.c doesn't reference symbols from rawmidi_virt.c
when SEQ support is not enabled.

libcurl: fix build on uncommon architectures

Since the bump to 7.55.0, libcurl fails to build on a number of
uncommon architectures (ARC, OpenRISC, etc.). This is due to upstream
commit 73a2fcea0b4adea6ba342cd7ed1149782c214ae3 ("includes: remove
curl/curlbuild.h and curl/curlrules.h"), which makes libcurl rely on
more architecture-specific related defines in include/curl/system.h.

This commit therefore adds a patch that fixes the 32-bit vs. 64-bit
detection for all architecture, using gcc's __SIZEOF_LONG__
definition. It has been tested successfully with test-pkg on all 47
toolchain configurations.

package/qt5base: only build libgtk3 support for X11 backend

swupdate: Lua 5.1 / LuaJIT are not supported

Before commit 87b6ac1478821351c92f7ca1c3154550e4713b28 support for Lua
was always disabled by the default config file:

```
CONFIG_LUA is not set
```

The commit removed this setting and Lua support is now enabled if a Lua
interpreter is enabled. As the swupdate build system uses pkg-config to
check for the lua library by default (LUAPKG="lua") this throws a lot of
undefined referenced in case LuaJIT is uses as Lua interpreter, e.g.:

```
corelib/lib.a(lua_interface.o): In function `l_info':
lua_interface.c:(.text.l_info+0x14): undefined reference to `luaL_checklstring'
```

In addition, since version 2017.07, Lua 5.1 really isn't supported any
more (before this version, it was only unsupported if the option
CONFIG_HANDLER_IN_LUA was set).  Therefore, remove support for Lua 5.1
and LuaJIT in the swupdate package for now until upstream might fix
this issue.

ficl: fix build with gcc 7

gcc 7 with -Os (optimize for size) takes the liberty to remove the code
of inline functions entirely - which is indeed allowed according to the
C99 standard, cfr. this [1] very complete StackOverflow answer. This
leads to undefined function references at link time.

The proper approach is to patch the code to use 'static inline'
instead. However, for various reasons such a patch is not entirely
trivial, and upstream has not moved since 7 years, so instead take the
simpler approach of restoring the gcc original inline behaviour with
-fgnu89-inline to fix this issue.

Revert "package/skeleton-custom: also check for missing directories"

This partially reverts commit cf6d321e9d5c9dec63e42466fec4bf5de5853bd3.

The underlying reason for doing the checks is to ensure that a
merged-usr setting is properly enforced, even for custom skeletons.

Before that patch, a custom skeleton where both /bin and /usr/bin were
missing was accepted; but then the first package that intalled something
in /bin would create it as a directory, thus breaking the merged-usr
situation. Ditto sbin and lib, of course.

cf6d321 was created to detect that situation, and the fix was to require
that both directories do exist in the custom skeleton, so that we new
the check for consistency were OK, in all cases.

However, that broke existing skeletons which where missing both
directories, and some people are shinning about it...

The crux of the problem is that Buildroot should be responsible for
creating the directories or the symliks when they are missing, and only
fail if the existing ones are incorrect, but not impose the burden on
the user.

A situation where the problem arises is when a skeleton is shared
between various builds, some using a merged-usr while other do not.

We fix that by reverting the offending changes change, back to the
previous behaviour. We keep the stderr redirection in stat calls, and
the variable renaming.

A proper fix to create the missing directories can be added later.

pkg-cmake.mk: set pkg-config env. vars. in the host configure environment

This change is fixing the bug reported in [1].

Cmake may run pkg-config to find the dependencies when configuring a
package. Because of the value of PATH, and it will use the Buildroot's
pkg-config wrapper, which, by default, is configured (via some
environment variables) to find the target dependencies.

When configuring a host package using cmake, to prevent cmake from
wrongly solving dependencies from the target tree (when the
*-config.cmake files are using pkg-config) instead of looking for them
in the Buildroot's host tree or in the host system itself, we need to
set the environment variables altering the pkg-config behavior in the
cmake configure environment.

So, this change is fixing the cmake host-packages configuration step,
by properly setting the pkg-config environment variables to their values
for finding host dependencies.

package/snappy: remove pthread handling for static builds

Commit 0e2ee0e6e8076 (package.snappy: fix static builds with threads)
added LIBS=-pthread to configure options to fix static build with
threads on some architectures. This works for autotools packages. Then,
commit d26282b3aa14cb (package/snappy: bump version, switch to cmake)
switched to cmake that does not understand the 'LIBS' parameter.

As pointed out by Thomas[1] the special handling of libpthread for
static builds is not needed anymore: it was needed only to build the
tests, and these are no longer built. Note that packages that link
statically with snappy will still need to link with -pthread. Only
two in-tree packages currently depend on snappy: lua-csnappy depends
on !BR2_STATIC_LIBS and leveldb adds -pthread from its build system.

Tested with the following musl & uclibc defconfigs which also fix build
errors:

gdb: drop support for Microblaze

Microblaze support was never upstreamed in gdb. We currently use a gdb
from the Xilinx Github repository, but this gdb is based on 7.6, and
has never been updated in the last 4 years. There are no other active
branches at https://github.com/Xilinx/gdb/branches.

Xilinx has a slightly newer gdb, based on 7.7, available at
https://github.com/Xilinx/meta-xilinx/tree/master/recipes-microblaze/gdb. However,
it's apparently only available in the form of stack of big patches
(https://github.com/Xilinx/meta-xilinx/tree/master/recipes-microblaze/gdb/files).

Currently, gdb on Microblaze fails to build in various conditions:

 * Against glibc, with "error: conflicting types for 'ps_lgetfpregs'"

 * Against musl, with "error: unknown type name 'elf_gregset_t'"

While those issues can probably be fixed, the fact that there is no
active upstream significantly reduces the incentive to fix those
problems.

Therefore, let's drop support for gdb on Microblaze entirely.

dbus: add upstream patch to fix startup hang with with expat >= 2.2.1

After c0ad6ded018ffbc33f7f5 expat: security bump to version 2.2.1
the system can hang on startup under certain circumstances.

This happens when:
  * we use systemd as init system
  * the random nonblocking pool takes a while to initialize
    * this apparently doesn't happen on qemu, so this would not have
      been caught by the runtime testing infrastructure
    * it also doesn't seem to happen when network booting

For a more detailed description of the bug see here:
https://bugs.freedesktop.org/show_bug.cgi?id=101858

cloog: remove package

This host-only package was used to enable graphite support in GCC 4.9,
but Buildroot no longer supports Graphite optimizations in GCC 4.9
(only GCC >= 5.x is supported). Therefore, we can remove the cloog
package.

isl: bump to version 0.18

Now that we no longer support Graphite optimizations in gcc 4.9 (which
required ISL 0.14.1), we can bump ISL to a newer version, which allows
to support Graphite optimizations in GCC >= 5.x.

The comment about the version being limited to 0.14.1 because of cloog
is no longer relevant, so it is removed.

Our libtool patch now applies properly, so we can remove

gcc: support grahite only for GCC 5 or above

GCC 4.9.x requires an old version of ISL to support graphite, and this
old version of ISL is not sufficient to support graphite in modern GCC
versions.

Since GCC 4.9.x is getting older, and to keep things simple, we stop
supporting graphite on old GCC < 5.x. This way, we will be able to
bump ISL to a version that is suitable for modern GCC versions.

In addition, this allows to drop the dependency on cloog, which was
only needed for GCC 4.9.

system: make systemd work on a read-only rootfs

When the rootfs is readonly, systemd will expect /var to be writable.
Because we do not really have a R/W filesystem to mount on /var, we make
it a tmpfs [*], and use the systemd-tmpfiles feature to populate it with
"factory" defaults.

We obtain those factory defaults by redirecting /var to that location at
build time, using a symlink /var -> /usr/share/factory which is the
location in which systemd-tmpfiles will look for when instructed to
"recursively copy" a directory.

With a line like:

    C /var/something - - - -

it will look for /usr/share/factory/something and copy it (recursively
if it is a directory) to /var/something, but only if it does not already
exist there.

We also mark this copy with the exclamation mark, as it is only safe to
copy on boot, not when changing targets.

To be noted: the real format for such lines are:

    C /var/something - - - - /from/where/to/copy/something

But if the source is not given, then it is implicitly taken from
/usr/share/factory (which in our case is as-good a location as whatever
else, so we use it, and thus we need not specify the source of the
copy).

Note that we treat symlinks a little bit specially, by creating symlinks
to the factory defaults rather than copying them.

Finally, /var at build time is a symlink, but at runtime, it must be a
directory (so we can mount the tmpfs over there). We can't change that
as a target-finalize hook, because:

  - some packages may want to set ownership and/or access rights on
    files or directories in /var, and that only happens while assembling
    the filesystem images; changing /var from a symlink to a (then
    empty) directory would break this;

  - /var would be a directory on sub-sequent builds (until the next
    "make clean").

Instead, we use the newly-introduce pre- and post-rootfs command hooks,
to turn /var into a directory before assembling the image, and back to a
symlink after assembling the image.

[*] People who want the factory-defaults only on first boot will have
    to tweak the fstab to mount something else than a tmpfs on /var.

fs: add pre- and post-command hooks

In some cases, the directory structure we want in the filesystem is not
exactly what we have in target/

For example, when systemd is used on a read-only rootfs, /var must be a
tmpfs. However, we may have packages that install stuff in there, and
set important rights (via the permission-table). So, at build time, we
need /var to be a symlink to the remanent location (/usr/share/factory)
while at runtime we need /var to be a directory.

One option would have been to have /var as a real directory even during
build time, and in a target-finalize hook, move everything out of there
and into the "factory" location. However, that's not possible because
it's too early: some packages may want to set ownership and/or acces
rights on directories or files in /var, and this is only done in the
fakeroot script, which is called only later during the assembling of the
filesystem images.

Also, there would have been no way to undo the tweak (i.e. we need to
restore the /var symlink so that subsequent builds continue to work) if
it were done as a target-finalize hook.

The only solution is to allow packages to register pre- and post-hooks
that are called right before and right after the rootfs commands are
executed, and inside in the fakeroot script.

We can however not re-use the BR2_ROOTFS_POST_FAKEROOT_SCRIPT feature
either because it is done before the filesystem command, but there is
nothing that is done after. Also, we don't want to add to, and modify a
user-supplied variable.

So, we introduce two new variables that packages can set to add the
commands they need to run to tweak the filesystem right at the last
moment.

Those hooks are not documented on-purpose; they are probably going to
only ever be used by systemd.

system: separate sysv and systemd parts of the skeleton

For systemd, we create a simple /etc/fstab with only an entry for /, as
systemd otherwise automatically mounts what it needs where it needs it.

systemd does not like that the content of /var be symlinks to /tmp,
especially journald that starts before /tmp is mounted, and thus the
journal files are hidden from view, which causes quite a bit of fuss...

Instead, move the current /var to a sysv-only skeleton.

systemd at install time will create the /var content it needs, so we
just create an empty /var for systemd.

systemd would create /home and /srv at runtime if they are missing, but
it is better to create them right now, to simplify supporting systemd on
a RO filesystem in the (near) future.

package/skeleton: introduce sysv, systemd and none specific skeletons

Currently, we use the same skeleton for sysv-like init systems and
systemd, even though systemd has some peculiarities that makes our
default skeleton unfit.

So, we'll need to provide different skeletons (really, only part of
it) for sysv-like and systemd. In addition, in order to support the
"no init system" (BR2_INIT_NONE) use case, we introduce a "none"
skeleton.

Introduce three new skeleton packages, aptly named skeleton-sysv,
skeleton-systemd and skeleton-none. All three are providers of the
skeleton virtual package, in lieu of the skeleton-common package,
which is now a simple dependency of all three new skeletons.

Those packages are empty for now. In followup changes:
  - sysv-specific stuff will be moved out of skeleton-common and into
    skeleton-sysv;
  - systemd-specific stuff will be added to skeleton-systemd.

package/skeleton-common: simplify staging install

We don't really care what's going in staging, as long as it is properly
setup for merged/non-merged /usr, especially for the lib/ directory.

So we can just copy the skeleton as-is.

This simplifies maintenance, should we ever need to tweak the layout:
we'd just have to do it once in the skeleton directory to have it
propagated to both target and staging.
