Many ports implement their own universal variant by manually creating this empty universal variant ("variant universal {}") and using get_canonical_archflags where needed.

Bummer, looks like "base" is trying to be too smart: the manually created variant is removed after the Portfile has been parsed, "due to < 2 supported universal_archs".
