Alexander Kanavin 51b4061048 ffmpeg: disable altivec on ppc by default
Since 4.3 ffmpeg uses vsx-specific instructions, which aren't
available on older ppc machines (including qemuppc):
3a557c5d88

This disables using the instructions with an option to re-enable them
for vsx-capable targets.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
