Thanks Robert. I actually like this one, because it does just what I'd 
want it to do, I think. Simply add -march=i486 to the default CFLAGS 
already present in the build system.

I'm getting ready to apply the change to Glibc, I'll hold off for a 
little bit to allow time for people to comment. And, of course, if we 
decide to use the above, I'll do a quick test run first.
