I really don't think we want to do this by default, at least not for 
i386.  Existing policy is to maintain the ABI, even doing so is not cheap.

I think we need a follow-up patch which removes the symbols which are 
now incompatible from the ABI, so that programs which are broken by this 
configuration receive an explicit error message.
