[Qemu-ppc] [PULL 57/64] ppc: Stop dumping state on all exceptions in linux-user |

From: Benjamin Herrenschmidt <address@hidden>
Other archs don't do it, some programs catch signals just fine
and those dumps just clutter the output. Keep the dumps for cases
that aren't supposed to happen such as unknown codes.
