[FFmpeg-devel] [PATCH] reuse extern_prefix for YASMFLAGS -DPREFIX

instead of the ugly hardcode, this sets yasm -DPREFIX when we detected something
for extern_prefix.
Actually this only works if extern_prefix is either not set at all or _,
anything else is currently not supported by the YASM code (though it would
be easy to extend).
