crossgcc: Add buildgcc support for Apple M1/M2 devices 

GMP and IASL don't compile with the default compiler and linker flags:
- GMP's check for the MacOS architecture hard coded x86_64 but it also
  needs to know about arm64.
- iasl does some trickery on pointer alignment to save space(?), so we
  need to tell clang about it.
