m68k with 4 bytes alignment works fine on NetBSD.

Which I don't care about because the current ABI is broken.

I'm not defending that system. I'm saying that I am not going to roll a custom
distribution of Debian because a few people on this list refuse to accept the
fact that the Linux/m68k ABI is broken and violates the official AT&T spec turning
the maintenance of this port more and more into a burden.
