Yeah, I'm thinking we could do

 -Wno-error=cpp

to at least allow the cpp warnings to come through without being fatal.

Because while they can be annoying too, they are most definitely under
our direct control, so..

I didn't actually test that, but I think it should work.

That said, maybe they should just be removed. They might be better off
just as Kconfig rules, rather than as a "hey, you screwed up your
Kconfig" warning after the fact.
