    libstdc++: Bump libtool_VERSION for GCC 16
    
    This should have been done in r16-995-gda9b2ea04c084d (or any of the
    later changes that added new symbols to trunk).
    
    libstdc++-v3/ChangeLog:
    
            * acinclude.m4 (libtool_VERSION): Bump version.
            * configure: Regenerate.
