	* gdb.threads/attach-into-signal.exp (corefunc): Don't enable
	lin-lwp output.  Set SIGALRM to stop.  Adjust tests to not rely on
	gdb's internal debug output.  For the non-threaded case, look for
	"Program received signal SIGLARM", for the threaded case, peek at
	the thread's siginfo.

        General cleanup, make output test messages unique, and build
        different executable files for the non-threaded and threaded
        cases.
