This was really odd.

I tried to figure out what was wrong with the toolchain and run `xcode-select 
--install` and `xcode-select --switch`. After the this, clang failed like what 
you mentioned.

I had to re-configure qemu with --extra-cflags="-isysroot `xcrun 
--show-sdk-path`”, forcing clang to use the correct SDK root, and then it would 
compile.

Thanks and best regards,
