PowerPC was the one outlier that defined both ELF_ARCH and ELF_MACHINE; ELF_ARCH was defined incorrectly, necessitating the definition of elf_check_arch. However, the elf file header field in question is called e_machine, so ELF_MACHINE is in fact the better name. Mechanically change most target/target_elf.h files, then adjust ppc/target_elf.h manually. Do not provide a default for ELF_MACHINE.
