[PATCH] uml: split CONFIG_FRAME_POINTER from DEBUG_INFO

Browse source 
Until now, FRAME_POINTER was set = DEBUG_INFO for UML.  Change it to be the
default way, so that it can be enabled alone (for instance to get better
backtraces on crashes).  The call-trace dumper which uses the frame pointer is
not yet in, I'm going to introduce it in a separate patch.
