ARM: Overhaul the ARM Makefile.
The ARM Makefile was copied from x86 and then modified, and as a result it
was carrying a lot of baggage. On top of that, the extra complication made it
inflexible, and we need a lot of flexiblity in order to support the fact that
the Tegra124 starts on an ARMv4 coprocessor instead of one of the ARMv7 main
CPUs.
BUG=None
TEST=Built and booted on pit. With this and other changes, built and booted
into the bootblock on nyan.
BRANCH=None
