Struct alignment hasn't changed (ARM changed theirs to match ours, as far
as we can tell).  I think the only possibly-relevant change is that enums
might end up different sizes, but I suspect there are no enums passed
across the user/kernel boundary anyway.

So sysinst will already notice a.out libraries and shift them to
/emul/aout when upgrading, or whatever the right thing is?
