 ENOEXEC here:
 ---
 int
 mips_netbsd_elf32_probe(struct lwp *l, struct exec_package *epp, void *eh0,
        char *itp, vaddr_t *start_p)
 {
  :
        switch (eh->e_flags & (EF_MIPS_ABI|EF_MIPS_ABI2)) {
 #if !defined(__mips_o32)
        case EF_MIPS_ABI2:
  :
 #endif
        case EF_MIPS_ABI_O32:
  :
        default:
                return ENOEXEC;
        }
 ---
 
 eh->e_flags is 0x0056, so
 eh->e_flags & (EF_MIPS_ABI|EF_MIPS_ABI2) == 0.
 
 Needs "case 0:" inside COMPAT_16 for ancient ELF binaries?
