yasm does not support AVX-512 and has very low activity recently[1].
nasm supports AVX-512 since 2.13[2]. Even if x265 does not use AVX-512
currently, this is the right way forward in the long run. It may be
possible to reduce the minimum required nasm version though, until
AVX-512 support is added.
BTW, x264 and ffmpeg made a similar move recently.
