Fix for the "help -[nD]" ELF header translation to recognize the
EM_ARM and EM_AARCH values as "e_machine" types, and ELFOSABI_LINUX
as an "e_ident[EI_OSABI]" type.  Without the patch, the e_machine
translation would show "40 (unsupported)" for 32-bit ARM, or
"183 (unsupported)" on ARM64; and the ELFOSABI_LINUX type would
be translated as "3 (?)".
