distcc: deprecate package, only useful for development

Since quite a while, we have deprecated, and then removed the support
to build a compiler on the target. Therefore, having a distcc package
for the package is quite useless, and this patch consequently marks it
as deprecated so it can be removed in a future version of Buildroot.

manual: add explanations on limitations about using O=...

Using a relative path for O=... has limitations, since it is interpreted
relative to the Buildroot tree, and thus may lead to unexpected results.

For example, running this:
    make -C buildroot O=my-O

will not create my-O in the current working directory, but as a
sub-directory of the Buildroot tree, here in buildroot/my-O

Explain this in the manual (as is similarly done for BR2_EXTERNAL).
Also add a note that $(O) will be created if missing.

Also change O=.. and -C .. to O=<...> and -C <...> to make it explicit
this is an ellipse, not a relative path.

manual: switch BR2_EXTERNAL examples to use absolute paths

Although it is possible to use relative paths, there are a few pitfalls
when doing so.

To avoid confusion for a (newcoming) user, use absolute paths in the
manual (as is done in examples for $(O)), since it is guaranteed to be
working without corner cases.

mpg123: needs MMU

mpg123 needs MMU because the application that is built with this

aiccu: disable on AVR32

In commit 87492d244a1dbf6114bb464e8d8dbedcf08fb399 ("aiccu: disable
for uClibc 0.9.31/0.9.32"), we made sure it was not possible to select
aiccu with uClibc 0.9.31 and 0.9.32, because they lack dn_skipname().

However, we still have the problem that external AVR32 toolchains can
select aiccu, which causes build failures. Therefore, we also disallow
aiccu on AVR32 altogether. We keep the 0.9.31/0.9.32 exclusions,
because if they are used on other architectures, it would also fail

evas: depend on thread support

Evas has an optional mechanism to do asynchronous preloading of
images. This mechanism is optional, and in commit
b6d92bf415df33ac86487d68f5f8299f406859d2 ("libevas: async image
preload support needs threads support in toolchain"), Peter made sure
to disable the asychronous preloading when no thread support was
available.

Unfortunately, it seems like disabling the asynchronous loading is
rarely used, and it in facts fails to build: a member of structure is
not present when asynchronous preloading is disabled, but the code
continues to use it.

Since the fix is not obvious, and all this mechanism seems to have
changed completely in EFL 1.8.x, and we probably don't care much about
EFL without threads, this commit adds a dependency of libevas on
thread support. Consequently, it also reverts commit
b6d92bf415df33ac86487d68f5f8299f406859d2 which is no longer necessary.

Of course, this commit propagates this additional dependency to the
reverse dependencies of libevas.

icu: not available when BR2_BINFMT_FLAT is used

icu does not recognize 'uclinux' as a supported platform. While making
it recognize uclinux is easy, there is another problem down the road:
icu does very weird things to generate an ELF library containing
static data (libicudata.a), and the generated library being ELF, it is
not compatible with the FLAT binary format expected by uclinux
platforms such as Blackfin in FLAT format.

Therefore, we simply disallow the selection of icu on FLAT
platforms.

Note that adding a dependency on BR2_BINFMT_ELF doesn't work, because
BR2_BINFMT_FDPIC is considered to be separate (even if technically
FDPIC is a derivative of ELF). That's why the dependency we're adding
is "depends on !BR2_BINFMT_FLAT" and not "depends on BR2_BINFMT_ELF".

host python/python3: conditionally disable unicodedata

The host python always had --disable-unicodedata, regardless of the
corresponding configuration option BR2_PACKAGE_PYTHON_UNICODEDATA.
Since the host python is used to byte-compile python modules, this meant
that such modules could not contain unicode strings. For example, following
statement in a python module:
    print u"\N{SOLIDUS}"

would cause the byte-compilation to fail with message:
    SyntaxError: ("(unicode error) \\N escapes not supported (can't load
    unicodedata module)",

Instead, conditionally disable unicodedata based on
BR2_PACKAGE_PYTHON_UNICODEDATA, also for the host python.

opencv: always enable opencv_core module when opencv is enabled

systemd: fix build with uClibc toolchains

Currently, the build of systemd is broken with the internal toolchain
backend, because we have uClibc patches that add support for
execvpe(), but we also have a patch for systemd that adds execvpe(),
which was added when the internal uClibc didn't support execvpe().

However, simply dropping the patch is not a solution, as it would
break the build of systemd with any other uClibc than the ones built
with Buildroot. For example, a Crosstool-NG uClibc toolchain would
fail.

Beyond this execvpe() problem, there are also other problems that
prevented systemd from being built with unpatched uClibc.

This patch does the following:

 * Add sequence numbers of systemd patches.
 * Regenerate them to avoid fuzz.
 * Improve the uClibc compatibility patch so that it:
   - Detects whether execvpe() is available or not, and if not
     available provide an implementation.
   - Detects if dup3() is available or not, and if not available
     provide an implementation.
   - Detects if MSG_CMSG_CLOEXEC is defined or not, and if not, define
     it to the appropriate value.

This has been tested with uClibc internal toolchain, uClibc external
toolchain built with Buildroot, uClibc external toolchain built with
Crosstool-NG, and glibc external toolchain.

Fixes bug #6776.

sdl: fix autoreconf timing issue

Context:
The autobuilders were failing on the symbol _XData32 being in conflicts.
A patch had been added to SDL to add a check to the configure.in

Problem:
Sometimes, the build would fail, because of an _XData32 symbol being in
conflicts eventhrough the patch was here.

What was happening:
Following the classic buildroot workflow:
   - Extract
   - [...]
   - Apply 001 patch, which touches configure.in AND configure
   - Apply 002 patch, which touches configure.in
   - Invoke autogen.sh
   - [...]

Right before running autogen.sh, we have configure.in which is more
recent than configure, which is fine.
We then, execute autogen.sh which, basically, runs autoconf.

If your machine was lighty loaded, the time difference between
configure.in and configure was really tiny (ms order), which seems to be
neglected by autoconf.
The results was that the configure was *NOT* generated. And our second
patch was not taken into account.

If your machine was under heavy load, the time difference between the
two files would have been greater and then *maybe* picked up by
autoconf. And then the configure file was re-generated.

When the 0001 patch was introduced, SDL package did *NOT* run it's
autogen.sh, which is why it touches also the configure.
This came later, causing this behavior.

Makefile.legacy: fix recursive invocation with BUILDROOT_DL_DIR and _CONFIG

The legacy support for the old BUILDROOT_DL_DIR and BUILDROOT_CONFIG
breaks down when make is invoked recursively - which is done in a few
cases, e.g. silentoldconfig, external-defs, ... These targets always
give a legacy error.

For BUILDROOT_DL_DIR, this is fixed by making sure that the original
value of BR2_DL_DIR taken from the environment is also exported again.

For BUILDROOT_CONFIG, this is fixed with an additional comparison of
the environment variable's value with the fake value that we introduce
ourselves.

Git repo version is taken from meta-ti.
It's a 3.12.10 kernel with TI's own patches on top.

The defconfig has been kept rather close to our old defconfig.
The kernel has been boot-tested using an NFS-root.

Apart from the kernel change, the linux headers has also been
updated from 3.8.12 to 3.12.10.

linux: don't automatically set uevent_helper with mdev /dev management

When mdev /dev management is chosen in the buildroot configuration, the
Linux configuration is updated automatically to set option
CONFIG_UEVENT_HELPER_PATH to "/sbin/mdev". However, the help text of this
option explicitly recommends not setting this option due to large
performance impact during boot (experienced first hand by the reporter ánd
author).

The mdev startup script S10mdev already sets the helper during userspace
boot, which will make sure mdev is working correctly.
