The reason behind not using ARCH_USE_MMU is that the
Microblaze core may not necessarily have a MMU. (The
MMU is an optional feature of the core).

The configuration is based on how the ARM architecture
uses the target processor choice in extra/Configs/Config.arm
for the various MMU/no-MMU processors.

If there's a better way to work with this, let me know and
I'll change it to suit.
