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