Revamp the ELF include files to better support architecture-independent
applications. Here's how it works. The kernel should include <machine/elf.h> to get the definitions for the native architecture. It can reference the various ELF structures with generic names like Elf_Sym, Elf_Shdr, etc. A define __ELF_WORD_SIZE is also available with the value 32 or 64 as appropriate for the native architecture. Generic applications should include <elf.h>, which is just a wrapper for <machine/elf.h>. Applications such as object file dumpers that need to deal with foreign ELF files can include <sys/elf32.h> and/or <sys/elf64.h>. Both can be included from the same source file if desired. The structure names must be referenced using wordsize-specific names like Elf32_Sym, Elf64_Shdr, etc. I haven't change the alpha stuff, but I haven't broken it either.
