COMPAT_NOMID (i.e. old ZMAGIC support) was introduced in August 1993
from i386, and I guess only hp300 was a functional m68k port at that time.
If COMPAT_NOMID is also required for old hp300 binaries, all m68k ports
should have it. (But such old binaries also require COMPAT_M68K4K??)
I don't know if hp300 had "a.out(5) executables that lack a machine ID,"
but anyway COMPAT_NOMID should be MACHINE_ARCH specific.
Maybe we should share cpu_exec_aout_makecmds() among all m68k ports.
(in m68k/m68k_machdep.c or elsewhere like mips/cpu_exec.c)
