WIP MachO binutils port assisted by AI
I may consider upstreaming this in the future.
buffer overflow in nds32_elf_lo12_reloc
nds32_elf_lo12_reloc reads the lo reloc word when processing stashed
hi relocs.
* elf32-nds32.c: Replace bfd_octets_per_byte with OCTETS_PER_BYTE
throughout file.
(nds32_elf_lo12_reloc): Sanity check reloc offset.
