# This makefile is constructed from a machine description:
# config machineid
# Most changes should be made in the machine description
# /sys/arch/sun3/conf/``machineid''
# after which you should do
# config machineid
# Machine generic makefile changes should be made in
# /sys/arch/sun3/conf/Makefile.sun3
# after which config should be rerun for all machines of that type.
# DEBUG is set to -g if debugging.
# PROF is set to -pg if profiling.
# XXX - Make cross-build work...
