description:
microSPARC-IIep is a sun4m but with an integrated PCI controller.
In a lot of places (like pmap &c) we want it to be treated as SUN4M.
But since various low-level things are done very differently from
normal sparcs (and since for now it requires a relocated kernel
anyway), the MSIIEP kernels are not supposed to support any other
system.  So when MSIIEP is defined - insist on SUN4M defined and SUN4
and SUN4C not defined.
