@oquenchil Could you review this small fix?

I have a very hard time reproducing this on the Bazel CI runners, so this doesn't come with a test. It shows up with Homebrew LLVM on GitHub Actions runners and without GNU readlink in path, which means that the readlink -f $CC logic doesn't run. I hope that this is uncontroversial enough to be merged as is.
