I was looking at ppc for ppc64. Adding some sort of /proc/self/auxv 
fallback to ff_getauxval() and then
re-writting all that to use ff_getauxval() and have support for 
FreeBSD/powerpc64 and OpenBSD/powerpc64.
FFmpeg is the only project I have come across so far that does not use 
getauxval() on ppc64.
