It can. And quite elegantly if I should say so :)

It now uses weak linking. Try to take a look at some of the Cortex-M* 
targets. The ARM RTL's haven't been converted yet, but I see no reason 
why they shouldn't be upgraded either. The new solution saves space and 
basically can't get any more efficient.
