    Add an explanation for --with-sysroot
    
    There are periodically users reporting that the --with-sysroot option
    does not exist in binutils and gcc. Add a note telling that not all
    aoptions are visible at the top level of the tree, unless
    --help=recursive is passed. Take --with-sysroot as an example, so
    that users have everything to find it...

+          to find the <option>--with-sysroot</option> option, you have to run
+          <command>ld/configure --help</command>. All the options can be
