I didn't have an aarch64 system handy to test when I sent my first patch, so I went with David's comment in an earlier thread that x86_64 and arm64 are supported. I did just fire up a Linux VM on my Mac and I see it does indeed report the arch as aarch64, and that it builds the self-tests without warnings. I'll mail a patch to translate the architecture as you suggest. - Ted
