Subject: compiler-gcc: hide COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW from sparse
Sparse doesn't support all the overflow builtins, so just hide them from
it to avoid lots of warnings/errors reported by it.
We could try to teach them to sparse, but the passed types are variable,
and sparse doesn't seem to handle that well.
