In gcc/opts.c at lines 1092-1102, I see

  if (flag_split_stack == -1)
    flag_split_stack = 0;
  else
    {
      if (!targetm.supports_split_stack (true))
        {
          error ("%<-fsplit-stack%> is not supported by "
                 "this compiler configuration");
          flag_split_stack = 0;
        }
    }
