can't build cross compilers on powerpc-apple-darwin5.5

[Alan Lehotsky <apl at alum dot mit dot edu>]

I'm trying to build cross compilers hosted on Mac OS X.  When 
configure puts together the
gcc/Makefile, it decides that it needs to look in darwin.c for 
garbage collection.

This is because config.gcc contains lines

	config_gtfiles="${config_gtfiles} \$(srcdir)/config/darwin.c"
	c_target_objs="darwin-c.o"
	cxx_target_objs="darwin-c.o"
	# Darwin linker does collect2 functionality
	use_collect2=no
	extra_headers=altivec.h

which (if I understand what's going on here) get triggered when 
config.gcc is called for the
HOST configuration.  When configure calls config.gcc for the TARGET, 
the damage is already done in
that the config_gtfiles shell variable is already contaminated.

Now, it seems to me that this config_gtfiles needs to be somewhere 
that ONLY affects targets, not where it affects the host environment 
and accidently affects the targets.....

I can't see how to fix this as long as the stuff is in config.gcc. 
In the old days, this stuff would be in
config/rs6000/x-darwin.  Is that where I should move it?
