# kern.post.mk
#
# Unified Makefile for building kenrels. This includes all the definitions
# that need to be included after all the % directives, except %RULES and
# things that act like they are part of %RULES
#
# Most make variables should not be defined in this file. Instead, they
# should be defined in the kern.pre.mk so that port makefiles can
# override or augment them.
