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.

If you say Y here the resulting kernel image will be slightly larger
and slower, but it will give very useful debugging information.
