kern.post.mk revision 92650 
1# kern.post.mk
2#
3# Unified Makefile for building kenrels.  This includes all the definitions
4# that need to be included after all the % directives, except %RULES and
5# things 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.
