There is already an octave-config script.  I don't know why you would
not have it on your system.

$ octave-config --help
usage: octave-config [options]

Options:

  -h, -?, --help        Print this message.

  --m-site-dir          Print the name of the directory where Octave
                        expects to find locally installed .m files.

  --oct-site-dir        Print the name of the directory where Octave
                        expects to find locally installed .oct files.

  -p VAR, --print VAR   Print the value of the given configuration
                        variable VAR.  Recognized variables are:

                          API_VERSION            LOCALARCHLIBDIR

You can also get some of the same information using mkoctfile --print VAR:

$ mkoctfile --help

  -DDEF                   Add -DDEF to compile commands.

  -lLIB                   Add library LIB to link command.

  -LDIR                   Add -LDIR to link command.

  -M, --depend            Generate dependency files (.d) for C and C++
                          source files.
