This is an updated version of the patch I sent on September 6 cleaning
up the um architecture's linker scripts. It differs from the previous
version only in having been rebased on top of Linus' current master.
This cross-architecture linker script cleanup project is in
preparation for adding support for building the kernel with
-ffunction-sections -fdata-sections, which is a prerequisite for
Ksplice.

um: Clean up linker script using standard macros.
