I have no idea why clang doesn't do this on its own, and why clang makes it so hard to query this path (-dumpversion returns something unrelated...). I know this is an ugly hack, but this is a very specialized script, so it should be OK to make it a bit hacky. Tested to work on Fedora (27) and Debian (unstable). Fixes #8428.
