        method.
        (Arm_relobj::section_needs_cortex_a8_stub_scanning,
        Arm_relobj::scan_section_for_cortex_a8_stubs,
        Arm_relobj::do_relocation_section): Instead of calling
        Output_section::output_address, use faster
        Arm_relobj::simple_input_section_output_address.
