There are a number of gcc "helper functions" in libc/arch/m68k/gen/*
that do not seem to be needed.  I'm refering to functions like:
	adddf3.S, addsf3.S, ashlsi3, ...

I haven't checked them all, but the machine description in the gcc
that is distributed with NetBSD seems to open code those functions.
If they are not going to be used, is there any reason to keep them?
