description:
make(1): mark strange code that calls exit(signo)

In other places, the exit status of make is carefully chosen to be 0
(success), 1 (did not make everything), 2 (other error).  Using a signal
number is not guaranteed to be consistent among operating systems and is
therefore a weird choice.
