To be honest, I don't have any clue why this is happening. This output seems to
happen before calling any code in opts-common.c as a result of the specs. But
why the specs will be touching -fdiagnostics-color=? I don't know much about
how the specs work.

If reverting the patch fixes the problem, please go ahead and just reopen the
bug fixed by it.
