      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/x68k/conf/``machineid''
      9 # after which you should do
     10 #	config machineid
     11 # Machine generic makefile changes should be made in
     12 #	/sys/arch/x68k/conf/Makefile.x68k
     13 # after which config should be rerun for all machines of that type.

     15 # N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
     16 #	IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
