7# This makefile is constructed from a machine description:
8#	config machineid
9# Most changes should be made in the machine description
10#	/sys/i386/conf/``machineid''
11# after which you should do
12#	 config machineid
13# Generic makefile changes should be made in
14#	/sys/i386/conf/Makefile.i386
15# after which config should be rerun for all machines.
16#
17# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE INVISIBLE TO MAKEFILE
18#	IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
19#
20# -DTRACE	compile in kernel tracing hooks
