[PATCH 9/9] [ld] Introduce new section flag: SEC_ELF_OCTETS


All symbols, sizes and relocations in this section are octets instead of
bytes. Required for DWARF debug sections as DWARF information is
organized in octets, not bytes.

	* ldlang (init_opb): New argument s. Set opb_shift to 0 if
	SEC_ELF_OCTETS for the current section is set.
	(print_input_section): Pass current section to init_opb().
	(print_data_statement,print_reloc_statement,
	print_padding_statement): Likewise.
	(lang_check_section_addresses): Call init_opb() for each
	section.
	(lang_size_sections_1,lang_size_sections_1,
	lang_do_assignments_1): Likewise.
	(lang_process): Pass NULL to init_opb().
