kern.post.mk revision 97160 
1# Part of unified Makefile for building kenrels.  This includes all
2# the definitions that need to be included after all the % directives,
3# except %RULES and things that act like they are part of %RULES
4#
5# Most make variables should not be defined in this file.  Instead, they
6# should be defined in the kern.pre.mk so that port makefiles can
7# override or augment them.
