s-osinte-linux-kfreebsd.ads (SC_NPROCESSORS_ONLN): New constant constant for sysconf call.

        * s-osinte-linux-kfreebsd.ads (SC_NPROCESSORS_ONLN): New
        constant 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.
        * Makefile.in: Use s-tasinf-linux.ads and s-tasinf-linux.adb
        on GNU/kFreeBSD.
