make: fixed stack limit bug (upstream fix)

bug #22010: The increased stack rlimit is inherited by the subprocesses to make.

        * make.h: Move SET_STACK_SIZE determination to make.h.
        * main.c (main): New global variable, STACK_LIMIT, holds the
        original stack limit when make was started.
        * job.c (start_job_command): Reset the stack limit, if we changed it.
        Fixes Savannah bug #22010.
