The content based uuid embedded by ld64 contains the basename of the file being built. In the case of multiarch builds this filename is randomly generated. This doesn't hit in all cases based on the order of the arguments to clang, but since this shouldn't have a downside for this use case, it's safer to exclude this for the future.
