Yes, I bumped a limited set of INC_PRs because the change affected only 
builds for x86_64 targets, and I think that usage is quite rare and 
probably limited to newer GCCs. I just didn't want to force everybody to 
rebuild when the vast majority are not building for 64.

It should in no way affect compatibility with other GCCs, other than that 
if someone is already using one to build for x86_64, their libgcc pkg will 
stay broken tilll they force a rebuild :)
