Thank you. I will try that.

AS was set to nasm because that's how my build process for FFmpeg has
run for years.

The build process is quite big, with lots of libraries with differing
requirements for build tools and env vars.
And the build creates static binaries for x86_64 linux, win and osx.
Today I'm adding aarch64 linux - currently everything works so long as
I --disable-asm in  x264 and ffmpeg.

I'll follow your guidance and see where I get.

Thank you very much.
