Before we apply this, I should probably do a round of randconfig tests. Right now,
I have a series that fixes all build errors we currently get from randconfig
(which always selects MULTIPLATFORM since it doesn't randomize choice statements),
but I am pretty sure that adding NOMMU into the mix gives us a lot of new errors.
