The check-package script when ran gives warnings on text wrapping
on all of these Config files. This patch cleans up all warnings
related to the text wrapping for the Config files starting with
the letter f in the package directory.
The appropriate indentation is: <tab><2 spaces><62 chars>

ffmpeg always enables support for nvenc/cuda even if their support
libraries are not present:
External libraries providing hardware acceleration:
cuda cuvid nvenc
[...]
Enabled hwaccels:
h264_cuvid mjpeg_cuvid mpeg2_cuvid vc1_cuvid vp9_cuvid
hevc_cuvid mpeg1_cuvid mpeg4_cuvid vp8_cuvid
This leads to a crash in freeswitch git master when transcoding video
streams on a system without nvidia hardware:
2017-07-22 15:06:27.306760 [INFO] avcodec.c:1077 initializing encoder 352x288
2017-07-22 15:06:27.306760 [NOTICE] avcodec.c:828 NVENC HW CODEC ENABLED
This patch disables the support of nvidia hardware acceleration support
for now until the needed packages are added to buildroot. For details

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.
