fix build on armv6

Hi,

clang enabled the integrated assembler by default and it breaks the build of gst-ffmpeg.

AS from base cannot assemble some c files, we need to use AS from binutils

Import libav upstream patch to fix cpu detection:
https://git.libav.org/?p=libav.git;a=commitdiff;h=8ee2b4672f6ad5cfd003e742f887cffcfea26021

The attached patch fixes that.

To apply the patch:
cd /usr/ports/multimedia/gstreamer-ffmpeg; patch < /path/to/patch
find /usr/ports/multimedia/gstreamer-ffmpeg -type f -name "*.orig" -delete

  Disable clang's integrated-as for this build.  Modify ARM assembly
  with upstream patch to handle different ARM revisions.  This fixes the build
  since the clang 3.5 import
