Does it fail the build if required options are missing? Specifically are
things like kCFI and IBT enabled? Silently not handling those will
result in an unbootable image.

As to missing mitigations; does it at least visibly warn people?

I'm very *very* uncomfortable having to 'support' a half-arsed compiler
like this.
