Log:
libgupc/
	* configure.ac: Check for backtrace additional libraries only
	if backtrace is enabled.
	* configure: Regenerate.
	* smp/upc_backtrace.c (__upc_backtrace): Change default trace
	file to 'backtrace.THREAD-ID'.
	(__upc-bactrace_init): Install backtrace signal handler only
	if backtrace is enabled for faults.
	(__upc_fault_handler): Do not announce signals, just restore
	signals, print backtrace, and return.  This causes a signal to
	be taken again, but this time monitor thread is informed.
	(__upc_fatal_backtrace): No need to check env variable as signal
	handler is conditionally installed.
