More recent versions compile nicely - just check them out.
Furthermore, if you add 

  # Mac OS X/arm64
  darwin*--arm64)
    XCFLAGS="$XCFLAGS -DNO_ASM"
    ;;

to src/makemake.in (for instance, just after the corresponding block for Mac OS X/x86_64) then it compiles even with generational garbage collection (if you have a proper libsigsev installed)! It passes all tests except some socket related ones which are known to give problems under macOS anyway also with intel CPUs.
