One additional question/point - which branch are you trying to build the cross
from?
I am sure it will not work from upstream master.
Unfortunately, owing to lack of free time… aarch64-darwin is not yet completely
ready to upstream, so folks are using the development branch here:
https://github.com/iains/gcc-darwin-arm64 (which I will update later, based on
the master version mentioned earlier; if testing goes OK).
