Brought in from p3.  If anybody knows good numbers for m68k COFF,
please let me know, or plug them in yourself.

	* Makefile.in, m68kcoff.sh, m68kcoff.sc-sh, config/m68k-coff.mt:
	added m68k-coff emulation mode, stolen from a29k emulation.
	Almost certainly wrong, but perhaps better than sun3.

Also fixed an error message in configure.in so that it started with
'***' like the other error messages do.
