    autoconf: Add information about the --x-* options to --help output
    
    Try to tell the user that the --x-* options are only used when the X
    libraries can't be found by pkg-config.

    autoconf: Tell the user about docs/autoconf.html in --help output
    
    The documentation in autoconf.html is much more explicit about how the
    different configure options control the build. This adds a notice at the
    end of the `./configure --help' output to tell the user about it.
