mpv/libmpeg2/libmpeg-0.4.1.diff
diego d8fccf4d46 Only compile and use libmpeg2 AltiVec code when AltiVec is available. The 
AltiVec code needs -maltivec to compile, but then AltiVec instructions
appear in other places of the code causing MPlayer to sigill.
Somehow upstream libmpeg2 manages not to sigill under what appear to be
the same circumstances. Enlightenment welcome.
