It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our Makefiles as part of the macros to determine when to do something in our Makefiles based on what phase of the build we are in. For consistency, bring this down to a single macro and use "$(PHASE_)" only. Signed-off-by: Tom Rini <trini@konsulko.com>
