Fix several mix up between octets and bytes in ELF program headers
Fixes additional locations not handled in the first patch. When converting between addresses in ELF headers [octets] and bfd LMA/VMA [bytes], the number of octets per byte needs to be incorporated. include/ * bfdlink.h (struct bfd_link_order): Add unit (bytes/octets) to offset and size members. * elf/internal.h (struct elf_internal_phdr): Likewise for p_align member. (struct elf_segment_map): Likewise for p_paddr and p_size members bfd/ * bfd.c (bfd_record_phdr): New local "opb". Fix assignment of "p_paddr" from "at". * elfcode.h (bfd_from_remote_memory): Add units to several parameters. New local "opb". Fix usage of p_align. Fix calculation of "localbase" from "ehdr_vma" and "p_vaddr". Fix call of target_read_memory. * elflink.c (elf_fixup_link_order): Fix scope of "s" local. Fix calculation of "offset" and "output_offset". (bfd_elf_final_link): New local "opb". Fix calculation of "size" from "offset" and fix calculation of "end" from "vma+size". Fix comparison between "sh_addr" and "vma"/"output_offset". (bfd_elf_discard_info): Fix calculation of "eh_alignment". * elf-bfd.h (struct elf_link_hash_table): Add unit to tls_size member. * elf.c (_bfd_elf_map_sections_to_segments): Add unit (bytes/ octets) to "wrap_to2 and "phdr_size" locals. Fix calculation of "wrap_to" value. Add unit (bytes) to phdr_lma variable. Fix assignment of p_paddr from phdr_lma. Fix comparison between "lma+size" and "next->lma". (elf_sort_segments): Fix assignment from p_paddr to lma. (assign_file_positions_for_load_sections): Add unit (bytes) to local "align". Fix calculation of local "off_adjust". Fix calculation of local "filehdr_vaddr". (assign_file_positions_for_non_load_sections): New local "opb". Fix calculation of "end" from "p_size".

Divide size by opb before checking align mask.
