Nope.  Elsewhere I unconditionally force pc-relative relocations:

    out_one (DW_EH_PE_pcrel | DW_EH_PE_sdata4);
...
  exp.X_add_symbol = fde->start_address;
  exp.X_op_symbol = symbol_temp_new_now ();
  emit_expr (&exp, 4);                          /* Code offset */

Which will be completely fixed up at link time.
