bug 10 -- embedded libltdl masks system version unconditionally

[Neil Jerram]

Hasn't this one been fixed by the change from AC_LIBLTDL_CONVENIENCE
to AC_LIBLTDL_INSTALLABLE?

        * configure.in: switch to AC_LIBLTDL_INSTALLABLE so we'll use the
        system libltdl when it's available.  Aside from the normal reasons
        to prefer installed shared libs, this means other apps that link
        with libguile and also use libltdl will be more likely to work
        right.
