It can't be correct in any file like bfd/elf-eh-frame.c or
binutils/dwarf.c that is compiled once but needs to support multiple
architectures.  Instead you should handle architecture specific dwarf
code at runtime using bfd_get_arch (and if necessary, bfd_get_mach).
See for example dwarf.c:init_dwarf_regnames_by_bfd_arch_and_mach or
the switch in elf-eh-frame.c:_bfd_elf_write_section_eh_frame on
abfd->arch_info->arch.
