4#
5# This makefile is constructed from a machine description:
6#	config machineid
7# Most changes should be made in the machine description
8#	/sys/arch/<arch>/conf/``machineid''
9# after which you should do
10#	config machineid
11# Machine generic makefile changes should be made in
12#	/sys/arch/arm/conf/Makefile.arm
13# after which config should be rerun for all machines of that type.
14
15# DEBUG is set to -g if debugging.
16# PROF is set to -pg if profiling.
