[Bug 1827819] [NEW] Systemtap stapconf header is not generated

[Raúl Vidal]

Public bug reported:

I upgraded from Ubuntu 18.10 to Ubuntu 19.04. Systemtap does not compile
scripts any more. It reports that stapconf_[random].h header file does
not exist. The Makefile in /tmp/stap[random]/ does exist, but for some
reason the C header is not being generated.

The systemtap script I am using contains the following probes:

global p_count = 0
    probe kprocess.create {
        p_count += 1
        //printf("Process: %s - PID: %d - Created PID: %d - Created TID: %d - Parent process: %d - Parent name: %s - Processes created: %d\n",execname(),pid(),new_pid,new_tid,ppid(),pid2execname(ppid()),p_count)
    }

    probe socket.create {
        printf("Process socket: %s - PID: %d - Parent process: %s - PPID: %d\n",execname(),pid(),pid2execname(ppid()),ppid())
    }

It worked in Ubuntu 18.10. But not in 19.04. I have compiled Systemtap
4.0 from source and reports the same error.
