    Fix errors in distclean and maintainer-clean
    
    The variable, LT_ARGZ_H, can be empty, which causes distclean and
    maintainer-clean to error as a directory is attempted to be removed
    instead of a file.
    
    When running maintainer-clean for gnulib-tests, the .version file is
    missing, which is needed by config.status, so the command will error.
    
    * configure.ac: Update CONFIG_STATUS_DEPENDENCIES to use dotversion so
      that the .version file can be generated if needed. Add AC_SUBST for
      LT_DOLLAR_SIGN use in libltdl/ltdl.mk.
    * libltdl/ltdl.mk: Add conditional to check if LT_ARGZ_H is empty.
