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).
