[Bug threads/11692] GDB internal error when using pthread_attr_setaffinity_np

Hmmm, problem is linux-thread-db.c is returning a minus_one_ptid to infrun when
this happens.  See:

WL: waitpid Thread 0xb7fe16c0 (LWP 22258) received Stopped (signal) (stopped)
LLW: trap ptid is LWP 22262.
infrun: target_wait (-1, status) =
infrun:   -1 [process -1],
infrun:   status->kind = spurious

  if (have_threads (ptid))
    {
      /* Change ptids back into the higher level PID + TID format.  If
	 the thread is dead and no longer on the thread list, we will
	 get back a dead ptid.  This can occur if the thread death
	 event gets postponed by other simultaneous events.  In such a
	 case, we want to just ignore the event and continue on.  */

      ptid = thread_from_lwp (ptid);
      if (GET_PID (ptid) == -1)
	ourstatus->kind = TARGET_WAITKIND_SPURIOUS;
    }

inferior -1 will obviously not be in the inferior table.

I'm not 100% certain what's best.  I've wanted to get rid of
TARGET_WAITKIND_SPURIOUS before, this may be the last drop.  :-)
