Comment (by kencu):

 Nothing likely ever requires m4 to be universal. However "+universal" will
 "accidentally" get passed to m4 if you try to install something else
 "+universal" that needs m4. In that case, "+universal" gets passed up the
 chain to all the build and lib deps, even if they don't need it or don't
 install any libraries.

 It's a difficult-to-fix-apparently failing of the way things work in
 macports.

 All you can do is install the obvious build-tool-deps first (cmake, m4,
 etc, etc) and then try to install your port +universal. Usually that will
 sort things out.
