What version of gcc? I use 2.7.2 and configured as
--target-m68k-coff. After configure is done, replace the generated
tm.h file with

	#include "m68k/m68k-coff.h"
	#define inhibit_libc

and build. The result is support libraries for targets with and
without floating point supports, and a variety of 680x0 processors.
