* libelf.h (elf_backend_data): Add fields elf_machine_alt1 and
elf_machine_alt2 which provide alternate versions of the machine
code.
* elf32-ppc.c (ELF_MACHINE_ALT1, ELF_MACHINE_ALT2): Define to
recognize old versions of the PowerPC machine code.
* elf32-target.h (elf32_bed): Initialize alternate machine code
fields defined by ELF_MACHINE_ALT1 and ELF_MACHINE_ALT2.
* elf64-target.h (elf64_bed): Initialize alternate machine code
fields defined by ELF_MACHINE_ALT1 and ELF_MACHINE_ALT2.
* elfcode.h (elf_object_p, elf_core_file_p): In addition to the
main machine code field, check the two alternate machine code
fields.
