    Fix builds on iq2000 and visium
    
    visium and iq2000 have libgloss configure bits that reference
    target_makefile_frag, but it's never set. This leads to failures during the
    configure process and an empty libgloss/<target>/Makefile.  Naturally bad
    things happen with an empty Makefile.
    
    This patch initializes target_makefile_frag for both targets in their
    configure.in files and updates the generated configure files.  This fixes the
    build failures.  I've been using it in my tester for about a week and both
    targets have flipped from consistently failing to consistently passing.
    
        * libgloss/visium/configure.in (target_makefile_frag): Define.
        * libgloss/visium/configure: Regenerated.
        * libgloss/iq2000/configure.in (target_makefile_frag): Define.
        * libgloss/iq2000/configure: Regenerated.
