ffmpeg already has an architecture exception for nios2. So we could
also replace that with a BR2_PACKAGE_FFMPEG_ARCH_SUPPORTS option, and
therefore easily add the exception for mips64r2/r6.

We're down to very few build failures per day, so I would really like
to get this issue out of the way, and see what other failures we have.
ffmpeg on mips64r2/r6 is now the #1 failure.
