there isn't a specific bug on the topic.  there are random ones where people 
try to emerge gcc and it errors out when building the 32bit ABI.  this is 
generally because they started off with a no-multilib profile and then later 
switched it a multilib profile.  we've just marked them as INVALID: install a 
multilib stage3 if you want multilib.
