Um.  I suppose what I meant was that if you use ar format, you should
be able to use ar as the tool to create and manipulate the things.
Which isn't really possible given the necessary alignment constraints
and the current design of ar.  I'm not sure whether I'd prefer adding
an option to ar to make it suitable or creating a similar format with
better alignment promises.

I do notice that this means that all ports have to know the largest
pagesize of any port...or at least of any port which can appear in fat
binaries.

Chris, do you do _anything_ besides hack NetBSD? :-)
