Why are you patching the toolchain instead of passing the correct parameters
to configure (--enable-cross-compile, --cross-prefix-..., etc)?

Looks OK.

Wrong fix.

http://git.libav.org/?p=libav.git;a=blob;f=configure;h=b139008d2b1aa5faea3f33c2a1922d0e1cb1fa5c;hb=HEAD#l2318

It should be fixed by passing the proper CPU to libav's configure as an argument.
