The mprotect changes are arch dependend, and as gimpy pointed out would
violate ABI on some archs. I don't see how implementing them (which would
be MD anyway) would cause any negative impact on other archs.

If some archs can not do it, fine (as Elad mentioned, we do the same for
non-executable stack already).
