PATCH RFA: New option: -fno-toplevel-order

Sorry if I was not clear.  What I meant was that, with Dan's patch 
(which implicitly enabled -fno-toplevel-reorder for all files), I had 
problems compiling newlib.  So, compiling newlib with 
-fno-toplevel-reorder for all files would be a further stress test for 
your patch.
