3# Part of a unified Makefile for building kernels.  This part includes all
4# the definitions that need to be after all the % directives except %RULES
5# and ones that act like they are part of %RULES.
6#
7# Most make variables should not be defined in this file.  Instead, they
8# should be defined in the kern.pre.mk so that port makefiles can
9# override or augment them.
