I agree. Since the environment is controllable, and if the bot starts
green while self-hosting, it's reasonable to assume -Werror can break
without problems.

The only problem is if both GCC and Clang have the same warning, and
fixing stage1 fixes stage2, we'd never know if Clang would have hit
the same assert.

But since this is regarding the build process, not Clang's warnings, I
think it's not a problem.
