It seems a bit odd that the ports system is pre-emptively blocking me from trying to build something that will work just fine, rather than providing a setting that allows the few ports that *are* architecture specific to declare themselves as such -- but maybe I'm misunderstanding what this feature does.

Ports like apache-ant that install no architecture-specific files should so indicate by using the key "supported_archs noarch".

I've fixed this for apache-ant just now:

http://trac.macports.org/changeset/74060

The vast majority of ports do install architecture-specific (i.e. compiled) files so it makes more sense to require the few architecture-agnostic ports to be modified.
