aarch64 2.7.2+ build on osx should work with the options listed at:
http://fate.ffmpeg.org/report.cgi?time=20151221193018&slot=arm64-osx10.9-apple-clang-n2.7

arm:
http://fate.ffmpeg.org/report.cgi?time=20151221184824&slot=arm-osx10.9-apple-clang-n2.7

maybe you can figure out which differences cause the failure ?
