The problem is that Darwin was emitting `macho_embedded` libraries under `usr/lib/clang/<version>/lib/darwin/macho_embedded`, but this change moved them to `usr/lib/clang/<version>/lib/macho_embedded`, so now the clang driver isn't able to find them.
I think using `COMPILER_RT_OUTPUT_LIBRARY_DIR` is the right thing, but we still want to be compatible with the existing layout unless we change the driver. I think changing the driver might be a better approach though, so I will try that.
