# Part of unified Makefile for building kernels.  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.
