kbuild: consistently decide when to rebuild a target
Consistently decide when to rebuild a target across all of
if_changed, if_changed_dep, if_changed_rule.
PHONY targets are now treated alike (ignored) for all targets
While add it make Kbuild.include almost readable by factoring out a few
bits to some common variables and reuse this in Makefile.build.
