Compile on Mac M1

[schoeberl]

Is there something related to x86 hardcoded?

      llvm::SPScope::SPScope(llvm::SPScope*, llvm::MachineLoop&, llvm::MachineFunction&, llvm::MachineLoopInfo&) in SPScope.cpp.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I looked at the code and as I expected there is no target dependent code I can find.
Maybe the problem is with the fact that this LLVM is from 2012 or so, so probably before there was any hint of mac on arm.
I'm noticing its saying "architecture arm64" and not mentioning OS, so maybe its assuming its unix?

Try to build the new compiler just to see if we get more useful errors?

PS. I don't think this is a problem with the Single-path code. I think it just happens to be the first submodule to be compiled.
