...and while we're talking about "questionable utility"...
COMPAT_AOUT_M68K, COMPAT_M68K4K, and COMPAT_VAX1K are merely exec glue (well,
mostly; COMPAT_AOUT_M68K has some ancient stat()-related emulation) for what
are, at this point, ridiculously old a.out binaries that you also need to have
the entire a.out runtime for.
I would say at this point that nobody has any business running these ancient
a.out binaries. All of these platforms switched to ELF **long** ago. Even
though these layers are extremely thin, a reasonable argument could be made
that these should go, too.
