Well, the patch looks fine to me to be honest I'm not sure what the
complaint is above... 

IE. On arch that define the new HAVE_NORMAL_FRAME_POINTER (let's just
call it HAVE_IMPLIED_FRAME_POINTER then :-)  we just don't do
-fno-omit-frame-pointer and avoid triggering the bug...

Segher, what are we missing here ?
