The Dejagnu doc contains two different tries at documenting how
to do remote testing:

Neither of those really hits the mark for me.  The script MkTestDir
referred to by releng.html isn't online anywhere,
and x319.html seems to put board config info in a default file
in a way that probably only allows remote testing on one target.

I still have never managed to execute a gcc test remotely, so I'm
writing a simple, complete example as I figure things out myself.
I'm purposely not using autoconf, automake, or the standard 'testsuite/'
convention in this example to keep the example simple, and reduce the
number of files the user needs to confront during the example.

I've written a pair of files test2.{c,exp} (see below).
Assuming PATH includes the current directory, the command
   runtest test2.exp
will compile and run test2.c, and perform three simple execution tests on it.

Then, assuming the fluffy cloud of magic config files is set up properly, the 
   runtest --target=s390-ibm-linux-gnu test2.exp
should do the same thing but build the test with the appropriate cross-compiler,
and run the test on a remote s390 system whose access info is in one of the 
config files.

Can anyone review test2.{c,exp} for correctness, and
give me hints about the smallest possible set of config files
needed to run this test remotely on two different targets
using telnet/ftp?

        printf("Exiting with status %d\n", atoi(argv[1]));
        return atoi(argv[1]);
