 I'm not a developer so I lack the experience to hack this into the source
 myself, but it would be useful on ARM systems which lack an FPU to have
 fast MP3 encoder support, by adding optional external support for this

 I found in my own testing that ''shineenc'' was 13x faster than LAME.
 Details here:

 The quality of the encode is supposedly worse than LAME, but encoding at
 320Kbps makes up for this and is still comparatively very fast. This would
 allow basic ARM systems such as the Marvell mv6282 SoC to transcode audio
 to MP3 in realtime - something they cannot currently achieve.
