Build: resolve error configuring FFMPEG on Linux

Browse Source 
Configure failed to find vorbis & vorbisenc on Linux with the errors:

ERROR: vorbis not found using pkg-config
ERROR: vorbisenc not found using pkg-config

the issue was caused by configures test program failing to link the test
code against the static library because functions in libm weren't found.

Resolve by adding `$libm_extralibs` to libvorbis.

Note that it's strange this issue didn't come up before,
since it occurs on a clean build it seems necessary.
