    nproc: Prefer sys/cdefs.h __unreachable over the builtin
    
    The __builtin_unreachable macro provided by Clang and GCC is a hint to
    the compiler used for optimization. The programs work fine even if the
    compiler doesn't support it. The sys/cdefs.h has had __unreachable for
    9 years (commit 732b31de5d9244bd1cc98192e09ee1881e9f55e9). It expands
    to the builtin if it is available. In the rare case that it is
    unsupported it expands to a null statement so compilation does not
    fail.
