Yes, kconfig.h itself shares the same problem, but it has generally
been just about the config option testing itself, so you'd normally
never care.

I'm not saying that fixing that too would be wrong, I'm just saying
that linux/compiler_types.h tends to have way more subtle stuff in it,
and get changed in ways that are not directly related to the config
options that we track other ways (ie our dependency making script very
much is all about those config options).
