[FFmpeg-devel] [PATCH] avcodec/x86/mpegaudiodsp: silence -Wunused-variable on --disable-mmx

[Ganesh Ajjanagadde]

This silences -Wunused-variable when compiled with --disable-mmx, e.g
http://fate.ffmpeg.org/log.cgi?time=20150919094617&log=compile&slot=x86_64-archlinux-gcc-disable-mmx.
The alternative of header guards will make it far too ugly.
