ffmpeg: mark as not available on nios2

ffmpeg was already marked as not available for the NIOS2 Sourcery
toolchains, but it could still be built with the internal toolchain
backend or a custom external toolchain.

However, an inspection of the latest glibc source code indicates that
FE_INVALID, FE_OVERFLOW and FE_UNDERFLOW and indeed not available in
the nios2 variant of <fenv.h>.

Consequently, this patch makes ffmpeg not available on nios2, which
allows to simplify a bit the dependencies.

It propagates this dependency to:

 - minidlna (and at the same time makes sure the minidlna comment is
   not displayed on nios2, which wasn't properly taken into account
   until now)
 - mpd
 - opencv
 - opencv3
 - squeezelite
 - tovid

Even if it selects ffmpeg, Kodi does not need an update since Kodi is
only available on a limited number of architectures (which don't
include nios2, obviously). Other packages only make use of ffmpeg when
available.

package/skeleton: ensure custom skeleton uses merged /usr if needed

When using systemd, the policy in Buildroot is to use a merged /usr
(see c5bd8af6, "system: add options for /bin /sbin and /lib to be
symlinks into /usr" for more info). So, we apply a few tricks in some
packages to account for the merged /usr case.

However, when using a custom skeleton, we have no say in how that
skeleton is organised, so it may well have a split /usr. In that case,
our little tricks might not work as expected.

So, when the user uses a custom skeleton and wants systemd as an init
system, we must check that the custom skeleton is setup with a merged
/usr.

We do that by checking that each pair of {/lib,/usr/lib} {/bin,/usr/bin}
and {/sbin,/usr/sbin} have the same inode numbers, i.e. /lib must have
the same inode number as /usr/lib (and so on...). When a pair does not
share the same inode number, this is not a merged /usr and we abort.

We implement that check with make constructs, so it is done very early
in the build process, and we can abort early if need be.

ruby: do not overwrite RUBY_CONF_ENV

In commit 53bf889cdca77979814bc6b74170e2f104fc3b70 ("ruby: should not
use dl_iterate_phdr() on Blackfin") we added
ac_cv_func_dl_iterate_phdr=no to RUBY_CONF_ENV when building on the
Blackfin architecture.

However, while doing so, we overwrote the previous value of
RUBY_CONF_ENV, which was defined to have custom CFLAGS:

RUBY_CONF_ENV = CFLAGS="$(RUBY_CFLAGS)"

This has no visible effect because the custom CFLAGS are only used on
SuperH/SuperH 64, while the overwrite of RUBY_CONF_ENV takes place on
Blackfin.

However, it doesn't look very pretty, and future additions to

system: Fix warning when selecting systemd and ensure merged /usr workarounds are enabled

With systemd and a custom skeleton, we end up with the following warning:

warning: (BR2_INIT_SYSTEMD) selects BR2_ROOTFS_MERGED_USR which has
unmet direct dependencies (BR2_ROOTFS_SKELETON_DEFAULT)

Which makes sense as the logic to install the symlinks to /usr is part of
the default skeleton handling, but the BR2_ROOTFS_MERGED_USR symbol is ALSO
used by packages to activate various workarounds for a merged /usr, so it
should be always active when using systemd even with a custom rootfs
skeleton (that by definition must use a merged /usr as required by systemd).

So introduce a dummy symbol with the same name for the custom skeleton case,
similar to how we handle the BR2_PACKAGE_BUSYBOX_SHOW_OTHERS option.

This is a hidden option so it can only be activated by enabling systemd (and
not if people just want to use a merged /usr with a custom skeleton but not
systemd), but as this is really a legacy option that is probably good enough
(if not, patches are welcome!).

pkgconf: fix incorrect variable-directory sysroot prefixing

According to the pkg-config documents ("specification") when
sysroot-prefixing is enabled via PKG_CONFIG_SYSROOT_DIR this should only
be applied to -I/-L directories (includes, library directories), and not
to all of the other variables that can specify a directory.

However xorg uses mapdir/sdkdir in a similar fashion in what could be
considered an abuse of the spec, hence needs to be prefixed as well.
And what's more, it also uses includedir in a nonstandard fashion just
requesting the value via 'pkg-config --variable=includedir libfoo' which
doesn't pass the standard prefixing rules for the --cflags and --libs
invocation.

This patch makes pkgconf behave in the pkg-config specified way with the
added exception for the includedir, libdir, mapdir and sdkdir variables
which are prefixed.

gauche: explicitly handle zlib

host-gauche currently fails to build if host-zlib was built before,

the LDFLAGS passed in the configure script (with -L
$(HOST_DIR)/usr/lib) are not passed all the way down to where -lz is

python3: add patch to fix PEP 3147 issue with automake built packages

Packages built with automake use a `py-compile` helper to byte-compile
Python source files. This script uses the "py_compile" module from the
standard library. In turn, the compile() function in the "py_compile"
module invokes the cache_from_source() function provided by importlib.

This commit adds a new patch named "020-importlib-no-pep3147.patch"
that changes cache_from_source() and source_from_cache() in importlib
to get rid of the "__pycache__" directory.

This commit fixes the following import error in kmod when the module
is built for Python 3:

  >>> from kmod import Kmod
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: cannot import name 'Kmod'

Moreover, this commit removes two patches that are no longer necessary
since modifying cache_from_source() and source_from_cache() disables
PEP 3147 for the standard library and distutils / setuptools.

package/libdcadec: enable shared build

The libdcadec package currently only builds a static library, which is
naturally built without -fPIC (since this is generally not needed for
static libraries).

However, when the generated static library gets used inside a larger
dynamic library, such as ffmpeg's one, the link fails, since we're
trying to include in a shared library non-PIC code.

To solve this, this commit changes the way the libdcadec library is
built to make sure a shared variant of the library gets built when
appropriate. This way, ffmpeg has a PIC-enabled libdcadec library to
link with.

libcurl is available. While indeed BR2_PACKAGE_CURL indicates that
libcurl is available, it is not the most appropriate option for this:
BR2_PACKAGE_LIBCURL is better. BR2_PACKAGE_LIBCURL indicates that
libcurl is available, while BR2_PACKAGE_CURL indicates that both
libcurl and the curl program are available. Only the former is needed
by Git.

core/pkg-generic: allow step hooks to fail a step

Currently, we touch our stamp files before we call the step hooks.
This means a step hook can not properly fail a step, since the stamp
file exists even if the hook exits in error, thus a subsequent 'make'
would not try to redo that step.

Fix that by calling the hooks before we touch the stamp files.

toolchain-external: make extraction idempotent

Commit 23ffa7ec first extracts to the toolchain-external build
directory and then moves everything to $(HOST_DIR)/opt/ext-toolchain.
However, this is not idempotent, because moving directories over
existing ones doesn't always work, particularly if the target is on
another device.

Simply remove the destination contents before moving.

arch/arm: VFP and Thumb1 are not compatible

gcc will refuse to build with both --with-mode=thumb and --with-fpu=vfp,
with error messages during ./configure, like:

    checking for suffix of object files... configure: error: in `/home/ymor
    in/dev/buildroot/O/build/host-gcc-initial-4.9.3/build/arm-buildroot-lin
    ux-uclibcgnueabihf/libgcc':
    configure: error: cannot compute suffix of object files: cannot compile
    See `config.log' for more details.

And config.log informatively contains:

    sorry, unimplemented: Thumb-1 hard-float VFP ABI

This is an error message that comes deep from gcc source files.

If gcc says it does not support VFP with Thumb1, then let's disable that
combination in our menuconfig.

Prefer VFP over Thumb1, i.e. hide Thumb1 when we're not soft-float.

docs/manual: do not override BR2_EXTERNAL

Currently, we forcibly override BR2_EXTERNAL when building the manual,
so as to avoid referring to packages therein from the manual.

However, when generating the lists of packages, we limit ourselves to
scanning for packages in (Buildroot's) TOPDIR and never search in
BR2_EXTERNAL. So, we do not really need to override BR2_EXTERNAL when
generating the manual to achieve the same result.

Furthermore, we're only looking for packages that are defined in the
sub-menu "Target packages", and never anywhere else, and especially not
in the sub-menu "User-provided options".

Finally, we're soon to completely eliminate use of BR2_EXTERNAL in
Kconfig altogether, so that would no longer have any impact anyway.

So, just leave BR2_EXTERNAL alone when generating the manual.

core: do not accept multiple definitions of a package

One of the selling points for br2-external is to provide a mean to add
new packages. However, it is not supported that a package be defined by
Buildroot and then redefined in a br2-external tree.

This situation may occur without the user noticing or even willing to
redefine the package, for example:
  - br2-external is first created against a version of Buildroot
  - a package (missing in Buildroot) is added to that br2-external tree
  - upstream Buildroot adds this package
  - user updates to the new Buildroot

In this case, the result in undefined, and we can't make any guarantee
on the result (working or not).

Add a sanity check so that a package redefinition gets caught.

toolchain/external: use generic extract commands (!blackfin case)

Now that packages can provide a list of files to be excluded when
extracting their archive, downloaded external toolchains are no longer
special in this respect.

Still, those toolchains are currently extracted directly into their
final location, $(HOST_DIR)/opt/ext-toolchain/ which means we still
need a custom extract command.

Except, we don't really need it: we can just move the toolchain, after
it's been extracted by the generic extract command, with a post-extract
hook.

This means that:

  - we now extract the toolchain with the generic extract command,

  - the toolchain is thus extracted into $(@D) ,

  - fixup commands are run against $(@D), as a post-extract hook,
    instead of against $(HOST_DIR)/opt/ext-toolchain ,

  - once this is done, we move $(@D)/* into the final location with a
    new post-extract hook.

Note: the blackfin case is special, and will be handled in a follow-up
patch.

[Thomas: register the TOOLCHAIN_EXTERNAL_FIXUP_CMDS only for the Arago
case, add some additional comments in the code about why we're moving
the toolchain around.]
