configs: fix build of calao_qil_a9260_defconfig

The Barebox, AT91Bootstrap and Linux patches for the Calao QIL A9260
board are all located in the same directory, board/calao/qil-a9260/,
with only a prefix to indicate to which component they apply.

Unfortunately, since commit 0eba4759fab9d093afacac77a0ac31f1f0b3cceb
("packages: apply custom patches using *.patch instead of
<pkg>-*.patch"), the logic to apply custom patches in Barebox and
AT91Bootstrap has been changed from applying <package>-*.patch to
applying *.patch (in order to be consistent with what we do for all
packages in Buildroot).

However, this had the effect of trying to apply both the AT91Bootstrap
and Barebox patches on both packages, which obviously cannot work.

This commit fixes that by moving patches around, and switching to use
BR2_GLOBAL_PATCH_DIR for all of Barebox, AT91Bootstrap and Linux
patches.

In addition, the defconfig was not specifying explicitly which Barebox
version to use, so right now it's trying to use Barebox 2015.09, on
which the board-specific patch does not apply. So we've forced to use
Barebox 2012.08, which was the lastest release available at the time
the defconfig was initially contributed.

python-numpy: re-enable for uClibc

In commit b0f025386f6861fdc21e38e3a33b65669276f2c2 a patch was added
to make sure that python-numpy does work in uClibc. This patch was
needed for the x86 architecture, because uClibc in fact does support
fenv for x86. However, we don't turn on this support in our uClibc
config. Because the Config.in depends still allowed uClibc for x86,
this lead to a built failure, which lead to the fix in commit b0f02538.
But since this fix also fixes it for all other (supported)
architectures, we can just remove the !uClibc dependency completely.

This is also propagated to the reverse dependency in opencv3.

ccache: support changing the output directory

When building in a different output directory than the original build,
there will currently be a lot of ccache misses because in many cases
there is some -I/... absolute path in the compilation. Ccache has an
option CCACHE_BASEDIR to substitute absolute paths with relative paths,
so they wil be the same in the hash (and in the output).

Since there are some disadvantages to this path rewriting, it is made
optional as BR2_CCACHE_USE_BASEDIR. It defaults to y because the
usefulness of ccache is severely reduced without this option.

In addition to CCACHE_BASEDIR, we also substitute away the occurences
of $(HOST_DIR) in the calculation of the compiler hash. This is done
regardless of the setting of BR2_CCACHE_USE_BASEDIR because it's
quite harmless.

ccache: use mtime for external toolchain, CONF_OPTS for internal toolchain

Our current ccache disables hashing of the compiler executable itself,
because using the default 'mtime' doesn't work in buildroot: we always
rebuild the compiler, so the mtime is always different, so the cache
always misses.

However, in the current situation, if a user changes the compiler
configuration (which would result in the compiler generating different
object files than before) and does 'make clean all', ccache may in fact
reuse object files from the previous run. This rarely gives problems,
because
(1) the cache expires quite quickly (it's only 1GB by default),
(2) radically changing compiler options will cause cache misses because
    different header files are used,
(3) many compiler changes (e.g. changing -mtune) have little practical
    effect because the resulting code is usually still compatible,
(4) we currently don't use CCACHE_BASEDIR, and almost all object files
    will contain an absolute path (e.g. in debug info), so when
    building in a different directory, most of it will miss,
(5) we do mostly build test, and many of the potential problems only
    appear at runtime.
Still, when ccache _does_ use the wrong cached object files, the
effects are really weird and hard to debug. Also, we want reproducible
builds and obviously the above makes builds non-reproducible. So we
have a FAQ entry that warns against using ccache and tells the user to
clear the cache in case of problems.

Now that ccache is called from the toolchain wrapper, it is in fact
possible to at least use the 'mtime' compiler hash for the external
toolchain and for the host-gcc. Indeed, in this case, the compiler
executable comes from a tarball so the mtime will be a good reference
for its state. Therefore, the patch (sed script) that changes the
default from 'mtime' to 'none' is removed.

For the internal toolchain, we can do better by providing a hash of
the relevant toolchain options. We are only interested in things that
affect the compiler itself, because ccache also processes the header
files and it doesn't look at libraries because it doesn't cache the
link step, just compilation. Everything that affects the compiler
itself can nicely be summarised in $(HOST_GCC_FINAL_CONF_OPTS). Of
course, also the compiler source itself is relevant, so the source
tarball and all the patches are included in the hash. For this purpose,
a new HOST_GCC_XTENSA_OVERLAY_TAR is introduced.

The following procedure tests the ccache behaviour:

 Use this defconfig:
BR2_arm=y
BR2_CCACHE=y

 make
 readelf -A output/build/uclibc-1.0.6/libc/signal/signal.os
-> Tag_CPU_name: "ARM926EJ-S"

 Now make menuconfig, change variant into BR2_cortex_a9

 make clean; make
 readelf -A output/build/uclibc-1.0.6/libc/signal/signal.os
-> Tag_CPU_name: "ARM926EJ-S"
 should be "Cortex-A9"

After this commit, it is "Cortex-A9".

By moving the ccache call to the toolchain wrapper, the following

gcc: use toolchain wrapper

We have a toolchain wrapper for external toolchain, but it is also
beneficial for internal toolchains, for the following reasons:

1. It can make sure that BR2_TARGET_OPTIMIZATION is passed to the
   compiler even if a package's build system doesn't honor CFLAGS.
2. It allows us to do the unsafe path check (i.e. -I/usr/include)
   without patching gcc.
3. It makes it simpler to implement building each package with a
   separate staging directory (per-package staging).
4. It makes it simpler to implement a compiler hash check for ccache.

The wrapper is reused from the external toolchain. A third CROSS_PATH_
option is added to the wrapper: in this case, the real executable is in
the same directory, with the extension .real.

The creation of the simple symlinks is merged with the creation of the
wrapper symlinks, otherwise part of the -gcc-ar handling logic would
have to be repeated.

The complex case-condition could be refactored with the one for the
external toolchain, but then it becomes even more complex because
they each have special corner cases. For example, the internal
toolchain has to handle *.real to avoid creating an extra indirection
after host-gcc-{final,initial}-rebuild.

Instead of creating the .real files, it would also have been possible
to install the internal toolchain in $(HOST_DIR)/opt, similar to what
we do for the external toolchain. However, then we would also have to
copy things to the sysroot and do more of the magic that the external
toolchain is doing. So keeping it in $(HOST_DIR)/usr/bin is much
simpler.

Note that gcc-initial has to be wrapped as well, because it is used for
building libc and we want to apply the same magic when building libc.

toolchain-external: move wrapper to toolchain directory

The toolchain wrapper will be reused for the internal toolchain, so it
belongs in the toolchain directory. Also, the ext- prefix is removed
from it. The build commands are moved to a new toolchain-wrapper.mk.

The wrapper arguments that are also relevant for the internal toolchain
wrapper are moved to toolchain-wrapper.mk, the rest stays in
toolchain-external.mk.

While we're at it, move the building of the toolchain wrapper to the
build step of toolchain-external. There is no specific reason to do
this, other than that it fits better semantically. Also remove the
MESSAGE call, otherwise we'd see:
>>> toolchain-external undefined Building
>>> toolchain-external undefined Building toolchain wrapper
/usr/bin/gcc ...
Having an extra "Building toolchain wrapper' message is pointless.

The useless condition on $(BR2_TARGET_OPTIMIZATION) is removed. It was
always true because it wasn't qstrip'ped first, so clearly it works
without that condition as well.

Also rewrapped some comments and removed the 'external' reference.

legal-info: allow to declare the actual sources for binary packages

The FOO_SITE/FOO_SOURCE variables usually point to a tarball containing
source code.

For the downloaded external toolchains this is not true, the "source"
tarball actually contains binaries. This is fine for making Buildroot
work, but for legal-info we really want to ship real source code, not
binaries.

Luckily, some (hopefully all) toolchain vendors publish a downloadable
tarball containing the source code counterpart for their binary
packages.

Here we allow the user to declare the URL of this other tarball in the
pair of variables FOO_ACTUAL_SOURCE_TARBALL (by default equal to
FOO_SOURCE) and FOO_ACTUAL_SOURCE_SITE (by default equal to FOO_SITE).
If the "actual source" package can be downloaded from the same
directory as the binary package, then only FOO_ACTUAL_SOURCE_TARBALL
needs to be set.

Note this change is not strictly toolchain-specific: it might be useful
for other packages that happen to ship binaries in the same way.

[Thomas:
  - remove "the source code has not been saved" warning that could
    never be triggered due to how the conditions were
    organized. Discussed with Luca live during the meeting.]

pkg-generic: prevent _SITE URLs with a trailing slash

A trailing slash in FOO_SITE is useless, since Buildroot automatically adds
a slash between FOO_SITE and the filename as appropriate.

Moreover it is potentially harmful, which led to introducing a workaround
to strip them:

    commit 1cbffbd015106ea90fe49e27433375769dc1035b
    Author: Shawn J. Goff <shawn7400@gmail.com>
    Date:   Fri Apr 12 09:40:30 2013 +0000

        eliminate double slashes caused by FOO_SITE ending in a slash

        When a FOO_SITE variable ends in a slash and gets joined with a
        FOO_SOURCE variable like $(FOO_SITE)/$(FOO_SOURCE), the resulting URI
        has a double slash. While double-slashes are fine in unix paths, they
        are reserved in URIs - the part following '//' must be an authority.

So let's ban trailing slashes entirely. They have all been removed in
a 7b0e757fb85fd, now add a check to error out loudly in case a new one
is added.

Example commands to test this check:

  $ make busybox-dirclean busybox-source
  rm -Rf /home/murray/devel/buildroot/output/build/busybox-1.23.2

toolchain-external: strip trailing slash from autogenerated FOO_SITE

Trailing slashes are going to be declared illegal from FOO_SITE
variables.

But Buildroot internally generates such a variable when using a custom
external toolchain (i.e. BR2_TOOLCHAIN_EXTERNAL_CUSTOM). This is
because TOOLCHAIN_EXTERNAL_SITE is set to
$(dir $(call qstrip,$(BR2_TOOLCHAIN_EXTERNAL_URL))), and $(dir)
leaves a trailing slash.

Fix it using patsubst, just like linux and the bootloaders do.

package/freerdp: fix missing define

glibc has two flavours of bits/termios.h: a genmeric one and an
architecture-specific one. When installing, glibc will install the
architecture-specific file if it exists, otherwise it installs the
generic file. Only Alpha, MIPS, PPC and Sparc have their own
bits/termios.h.

The generic bits/termios.h, as well as the Alpha, PPC and Sparc flavours
do define CMSPAR. However, the MIPS flavour does not define it.

We add a patch to FreeRDP that defines CMSPAR to the value from the
generic value, which is also the value known to the Linux kernel for
MIPS.

gmock: new package

Inspired by jMock, EasyMock, and Hamcrest, and designed with C++'s
specifics in mind, Google C++ Mocking Framework (or Google Mock for
short) is a library for writing and using C++ mock classes.

Google Mock:

  * lets you create mock classes trivially using simple macros,
  * supports a rich set of matchers and actions,
  * handles unordered, partially ordered, or completely ordered
    expectations,
  * is extensible by users, and
  * works on Linux, Mac OS X, Windows, Windows Mobile, minGW, and
    Symbian.

  http://code.google.com/p/googlemock/

There are both host and target packages. The target one has include
files required to compile the tests and the static libraries required
to link/run them. The host package installs gmock_gen, a Python script
used to generate code mocks.

Notice that GMock 1.7.0 requires the Python 2 host package even if
Python 3 is selected as a target package.

swupdate: provide sensible error message if no config file is specified

package/swupdate: new package

swupdate provides a reliable way to update the software on an embedded system.

Note that swupdates has a reworked Kbuild/Kconfig system. It has now support
for the 'option' and 'env' symbols as well for the 'savedefconfig' target.
This makes dependency handling much easier. We're now able to pass which
dependencies are available through the environment, as suggested by Arnout
Vandecappelle [1].

In previous version of this patch we had a configuration setting where all
package dependencies except Lua were selected by default. This has changed with
v7 as we are now able to pass dependencies to the swupdate build system through
the environment. For useful operation swupdate requires a parser which depends
by default on libconfig, but can be replaced by a json-c or Lua parser.

To provide a reasonable firmware update system we enable the embedded webserver
based on mongoose (also see notes about mongoose below), a parser as stated
above and a handler for raw NAND or NOR flash.

The user can modify this configuration by selecting the appropriate dependencies
before running `make swupdate-menuconfig`. The help text contains information
about which packages may be of interest for the user.

The embedded web server requires a website for proper operation. We install the
included website by default, however the user may choose to install a custom
website on the post-build scripts.

Note, swupdate includes some old versions of mongoose and lsqlite3:
  - mongoose is version 3.8 from year 2013
  - lsqlite3 is version 0.8 from year 2011

Currently, swupdate does not provide a way to replace these with external
packages.

This patch is based on a WIP version submitted by Romain Naour, commented by
Arnout Vandecappelle [2].

skeleton: fix absence of /dev/shm on static, read-only systems

/dev/shm is needed for systems using shared memory. On init-based systems
this directory is usually created in the inittab along with /dev/pts, by
the lines:

package/busybox/inittab:
  ::sysinit:/bin/mkdir -p /dev/pts
  ::sysinit:/bin/mkdir -p /dev/shm

package/sysvinit/inittab:
  si2::sysinit:/bin/mkdir -p /dev/pts
  si3::sysinit:/bin/mkdir -p /dev/shm

However this is broken when static /dev management is selected and the root
filesystem is read-only, showing during boot the error:

  mkdir: can't create directory '/dev/shm': Read-only file system

Fix it by creating the empty /dev/shm directory, just like /dev/pts.

valgrind: build for the right MIPS ISA revision level

When Valgrind detects a 32-bit MIPS architecture, it forcibly adds
-march=mips32 to CFLAGS; when it detects a 64-bit MIPS architecture, it
forcibly adds -march=mips64. This causes Valgrind to be built always for
the first ISA revision level (R1), even when the user has configured
Buildroot for the second ISA revision level (R2).

Since R2 is backwards compatible with R1, you can run a Valgrind built
for R1 in an R2 core. This is why nobody noticed about this problem, or
at least nobody complained.

But, since (I hope) we will support R6 in Buildroot in the near future,
this problem will become very important because R6 is not backwards
compatible with R1 or R2, so building Valgrind for R1 when your target
is R6 will result in a non-working Valgrind.

Override the CFLAGS variable (which Valgrind appends to its CFLAGS) and
pass the right -march option, so they take precedence over Valgrind's
wrongfully detected value.
