config path

[James R. Van Zandt]

Ben -

The pspp docs say:

            c. Otherwise, the compiled-in fallback default is used.
            On UNIX machines, the default fallback path is

                 1. `~/.pspp'

                 2. `/usr/local/lib/pspp'

                 3. `/usr/lib/pspp'

Actually, in version 0.3.0, the default path consists of only the
first of these directories.  src/Makefile adds "$(pkgsysconfdir)".
However, that make variable has not been set to anything.  (The
variable is set in config/Makefile however.)

In the Debian package, I have set pkgsysconfdir to "/etc/pspp".
