S/390: Rename __S390_ARCH_LEVEL__ to __ARCH__.
We have recently added the predefined macro __S390_ARCH_LEVEL__ to
expand to a numerical value representing the architecture document
level currently in use. However, the IBM XL compiler already has a
macro named __ARCH__ for that purpose. So we change our macro to that
in order to improve portability.
