Rust is blocked on libffi, as are most things using Python (which includes cmake, and that precludes all of LLVM). I downloaded the Go bootstrap and it tried to link against crt0 directly and it's either looking up the wrong one or there is none for aarch64. It's also looking for a file called defs_darwin_arm.h which I don't have. Some warnings that will probably be problematic at the future related to the ABI defining char to be signed.

Go team was already working on getting the toolchain to work on darwin/macOS before Apple announcement[1] because GOOS=darwin meant iOS(gomobile) and there are instructions available now[2] to build it successfully before the official patches. Your test results there would be a valuable contribution.

You mean unsigned char? that's a common hurdle while porting x86 code to ARM.
