MacPorts adds a universal variant by default, which works with ports using autoconf or something like it. If you use "use_configure no", you're indicating to MacPorts that this port uses something that isn't anything like autoconf, so that default universal variant goes away, and you get to program one yourself. You already did all the work: you used [get_canonical_archflags] in the right place to tell the build system what archs to use. All that was missing was a declaration of a universal variant, which causes the universal variant to show up in "port info" and "port variants", and causes [get_canonical_archflags] to return the universal archs when the universal variant is selected.
