From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> 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.
