m68k coldfire causes ffmpeg to think atomic intrinsics are available,
so ffmpeg doesn't use its fallback on pthreads based atomic
operations. However, m68k coldfire doesn't provide properly working
sync 4 atomics, causing a build failure.
Since fixing ffmpeg on m68k coldfire is not really important (who
wants to use ffmpeg on such platform?), we simply disallow the
selection of ffmpeg on this platform.
Alternate approaches have been proposed in the past:
- Bernd Kuhls proposed in http://patchwork.ozlabs.org/patch/766909/
to add a dependency on BR2_TOOLCHAIN_HAS_SYNC_4, but this is wrong
because other architectures that lack sync 4 atomics, such as
Sparc, can build ffmpeg perfectly fine thanks to the pthreads based
fallback code.
- Waldemar Brodkorb proposed in
https://patchwork.ozlabs.org/patch/756664/ to add an explicit
option in ffmpeg configure to force the use of pthreads based
atomics. However, we believe that running ffmpeg on m68k coldfire
is such an unlikely use case that it isn't worth carrying a patch
for this.

The check-package script when ran gives warnings on ordering issues

The current logic to pass the --{enable,disable}-mipsfpu option is:
ifeq ($(BR2_MIPS_SOFT_FLOAT),y)
FFMPEG_CONF_OPTS += --disable-mipsfpu
else
FFMPEG_CONF_OPTS += --enable-mipsfpu
endif
In practice, this means that on MIPS soft-float, --disable-mipsfpu is
passed, and that in *all* other cases, --enable-mipsfpu is passed,
including if we are *not* targetting the MIPS architecture.
Even though this doesn't seem to cause any problem, it is a bit weird to
see --enable-mipsfpu when you're building ffmpeg for a non-MIPS
architecture, so we better fix this by enclosing the MIPS-related
options in a MIPS condition.

When BR2_ARM_CPU_HAS_NEON=y, we pass --enable-neon. However, when
BR2_ARM_CPU_HAS_NEON is disabled, we don't pass anything. This generally
works fine, but turned out to integrate NEON code in ARMv7-M
builds (since it's ARMv7, ffmpeg assumed it should enable NEON code).
Even though ffmpeg is now disabled for ARMv7-M, it still makes sense to
be explicit, and disable NEON support when the CPU doesn't have it.

In the ffmpeg code, libavutil/arm/asm.S makes some assumption about the
ARM architecture for which the code is built. Only ARMv4, ARMv5, ARMv6
and ARMv7-A is supported. Due to this, object files built out of
ARM-optimized assembly code have the wrong architecture information,
causing a failure at link time.
Adding ARMv7-M support would be possible, but it doesn't exist yet in
ffmpeg, and it's pretty unlikely that ffmpeg will ever be needed on an
ARMv7-M platform, so this commit takes the simple approach of disabling
ffmpeg for ARMv7-M.

MIPS architecture detection is not accurate and is always detected as
mips64 even if we are using mips64r2 or mips64r6. Due to that, ffmpeg's
build system will pass the -mips64 flag which will conflict with the
-march option that our toolchain wrapper uses, and it will fail to build
showing errors like this one:
error: '-mips64' conflicts with the other architecture options, which
specify a mips64r2 processor
This problem has been already fixed upstream, but we would need to
backport 17 patches plus some changes in the ffmpeg.mk file. This is too
much, so better to just disable ffmpeg for mips64r2 and mips64r6 for the
upcoming Buildroot release.
This commit can be reverted in the next ffmpeg's version bump.

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.
