No functional change, albeit all globals now become hidden, and aliasing
symbols (__aeabi_{u,}idiv) lose their function-ness and size.

If the function-ness was important (Julien says it likely isn't), some
new construct would need inventing. Not setting size for the aliases may
even be desirable, as I'm uncertain whether it is really legal in ELF
that two entities overlap in space.
