Due to some buggy AltiVec code present in FFmpeg 4.2.2, base clang can
not successfully build. Base gcc however has no issues in doing so.
I have tried patches linked at this URL
https://trac.ffmpeg.org/ticket/7861 . This allows base clang to build
a broken FFmpeg that gives a floating point exception error when
converting a file. For these reasons, I believe using base gcc is the
best solution.
Only tested on OpenBSD 6.7 macppc.
