<pre>
    I like to build `clang+llvm-15.0.7-x86_64-apple-darwin21.0.tar.xz` myself for llvm16 and llvm17,  It will be great if there is a one click script to do it all.


If there is a options to build libclang_rt.*.a libunwind.a, libc++.a  for intel X86-64 and apple M1/M2 will solve a lot trouble for apple user,  in this case I can use intel X86-64 cross build M1/M2 app.   (or crosss build X86-64 app from M1/M2)
