Hmm. I was looking at removing a.out support entirely, but it's
actually fairly incestuous on alpha.

For example, arch/alpha/boot/tools/objstrip.c very much has some a.out
support in it. Maybe it can just be removed entirely.

There's also an a.out.h include in arch/alpha/kernel/binfmt_loader.c.

Finally, note that CONFIG_OSF4_COMPAT also no longer makes sense
without a.out support.

So this attached patch does not compile on alpha, but it's been many
many years since I had an alpha to test with, so I'm stuck.

Matt, can you fill in the details and complete this patch?
