Hi,
the problem is in cgraph_only_called_directl_p call within
call_abi_of_interest.
Getting the one can probably fix the problem by:
Index: rs6000.c
===================================================================
--- rs6000.c    (revision 175166)
+++ rs6000.c    (working copy)
@@ -7419,7 +7419,7 @@ call_ABI_of_interest (tree fndecl)

       /* Interesting functions that we are emitting in this object file.  */
       c_node = cgraph_get_node (fndecl);
-      return !cgraph_only_called_directly_p (c_node);
+      return !cgraph_only_called_directly_p (cgraph_function_or_thunk_node
(c_node, NULL));
     }
   return false;
 }

however I can't make sense of the logic here.  Doesn't it want to use 
c_node->local && c_node->can_change_signature
like other ABI change issues?  It makes it possible to use modified ABI cross
ltrans partitions.
