We'll hopefully this thread might spark either an explanation for why  
we aren't just linking libgcc in a statement that says we should and  
we can remove the code that implements libgcc functionality.

How would libgcc linking intermix with modules?  Would we have to  
EXPORT_SYMBOL() all functions that libgcc implements?  I'm guessing  
that's varies w/different gcc versions.
