    top-level: Fix comment about --enable-libstdcxx in configure
    
    The custom option for enabling/disabling libstdc++ is not spelled the
    same as the directory name:
    
    AC_ARG_ENABLE(libstdcxx,
    AS_HELP_STRING([--disable-libstdcxx],
      [do not build libstdc++-v3 directory])
    
    The comment referring to it later use the wrong name.
    
    ChangeLog:
    
            * configure.ac: Fix incorrect option in comment.
            * configure: Regenerate.
