PR ada/34466

	* s-osinte-linux-hppa.ads (SC_NPROCESSORS_ONLN): New constant for
	sysconf call.
	(bit_field): New packed boolean type used by cpu_set_t.
	(cpu_set_t): New type corresponding to the C type with
	the same name. Note that on the Ada side we use a bit
	field array for the affinity mask. There is not need
	for the C macro for setting individual bit.
	(pthread_setaffinity_np): New imported routine.
