Lots of build system cleanup and documentation This splits mk/stageN.mk into host.mk and target.mk and makes the build rules somewhat simpler - there's no more building from stageN into stageN+1; instead we always build from stageN(host) to stageN(target) then promote from stageN(target) to stageN+1(host). Add a big honkin explaination right at the top of Makefile.in

# TARGET_STAGE_N template: This defines how target artifacts are built
# for all stage/target architecture combinations. Argument 1 is the
# stage and arg 2 is the target triple
# FIXME: We don't actually know how to build many of these when host
# and target architectures are not the same
