2000-11-22 Oliver Rauch <Oliver.Rauch@Wolfsburg.DE>

* changed configure.in, configure frontend/Makefile.in
          and backend/Makfile.in:
          The shared libraries required by the backends are linked to
          the backends (they have been linked to the frontends before).
          Only libintl is linked to the frontend.
        * changed tool/sane-config.in, sane-config --libs => "-lsane",
          all other libraries are linked to the backend libs now

configure.in
