fix arm build with asm disabled and add cpu flag detection for linux, android and ios (!275) · Merge requests · VideoLAN / dav1d

Janne Grunau requested to merge janne/dav1d:fix136 into master Oct 31, 2018

Detection on ios is fake, assumes NEON is always available. Linux and android use getauxval. Was added to android api level 18. @mstorsjo I guess for windows on arm we can also assume that neon is available.

@jbk do we care about any other OS or older android releases?
