* s-osinte-linux-alpha.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.
