Yeah Sasha's fix works w/o eliding the FP routines (there's an unrelated 
issue which I send a fix for [1])

As of 7.4-rc1, I have 2 ARC only changes to
1. Switch to existing in-tree GENERIC_LIB*
2. Dropping FP symbols

I can post them now. Once Simon's changes land, lefover ARC conversion 
and and removal of libgcc can all go together via your tree if that's OK 
with you.
