    Remove vestiges of --with-stabs
    
    This removes the --with-stabs configure option which had no effect
    since quite some time.
    
    2021-09-10  Richard Biener  <rguenther@suse.de>
    
            * configure.ac (--with-stabs): Remove.
            * configure: Regenerate.
            * doc/install.texi: Remove --with-stabs documentation.
