Well, that's quite problematic as I handle_common_deferred_options is called
after decode_options (that calls finish_options).

Note there's direct dependency at very end of finish_options in between -gtoggle
and debug_nonbind_markers_p:


   if (flag_gtoggle)
     {
       if (debug_info_level == DINFO_LEVEL_NONE)
	{
	  debug_info_level = DINFO_LEVEL_NORMAL;

	  if (write_symbols == NO_DEBUG)
	    write_symbols = PREFERRED_DEBUGGING_TYPE;
	}
       else
	debug_info_level = DINFO_LEVEL_NONE;
     }

   if (!OPTION_SET_P (debug_nonbind_markers_p))
     debug_nonbind_markers_p
       = (optimize
	 && debug_info_level >= DINFO_LEVEL_NORMAL
	 && dwarf_debuginfo_p ()
	 && !(flag_selective_scheduling || flag_selective_scheduling2));

I don't see who you mean the possible fix?
