   Is it possible to make gcc for a Sun4 that will produce an

To make 68k binaries on a SPARC (seems to be working so far), I added
a target to config.gcc that looks something like

	case $machine in
	...
	my68k)
		cpu_type=m68k
		configuration_file=xm-sparc.h
		target_machine=tm-my68k.h
		aux_output=out-m68k.c
		;;

Then I just say "config.gcc my68k" and make it (one stage only :-).
You'll need a cross-gas too (quite a bit simpler), and a cross-gld
(which gets more interesting, depending upon your target machine...)
