Compile LyX on Apple Silicon / arm64

Hi Stephan,

looking around for a way to create universal binaries for arm64/x86_64
outside of XCode I've stumbled onto this project here:
If it works the way the Readme makes it sound, it should be fairly simple
to create a universal binary in the existing LyX build environment. I'll
try to find some time to play around with it a little over the next few

I only had to make the tiniest change in to get
it to run on Big Sur (macos SDK version 10.x vs. 11.x). I attached a patch
for it.

Best regards,
