@rorth, I just checked and my local config has `LLVM_ENABLE_PROJECTS:STRING=clang;compiler-rt`. It installs this as you said `./lib/clang/23/lib/darwin/liborc_rt_osx.a`, however, the current main branch works fine because, as I mentioned, clang is smart enough to that location back. I will run on linux.
