* exec.c (check_elf): Call elf_machine_matches_host instead of
comparing against elf_machine.
(load_section): #if 0 out no-op code that uses elf_machine.
* priv.h (elf_machine_matches_host): Declare it.
(elf_machine, mach_host_elf_machine): Remove decls.
* main.c (main) [!BFD]: Don't call mach_host_elf_machine.
(elf_machine): Variable removed.
* exec.c (map): Don't cast arg to munmap to vm_address_t.
