Add ElfW() macro for compatibility with Linux

Description

Add ElfW() macro for compatibility with Linux

Some Linux software using ELF headers assumes the existence of an
ElfW(type) macro, which concatenates 'Elf', the default ELF word size,
and the given type. This is identical to our ElfN(x) macro in
<sys/elf_generic.h>. Add the macro for compatibility, with a comment
that we prefer the
ElfN() macro for FreeBSD.
