Red Hat is working on code to look in

/opt/sparc64-cross/sparc64-linux/sys-root/usr/lib64/crtn.o

and so on for such things---essential if you also have a

/opt/sparc64-cross/sparc64-linux/sys-root/usr/lib/crtn.o

and want to be able to write -m32 and have it just work.  It's not
done yet.  I don't think it'd be a waste of time to try to implement
it again especially if you can learn from the successes of the current
patch (and are told where all the land mines are in advance...).
