Pythons +universal: advice needed, should I submit a PR or not?

[barracuda156]

I have finally fixed Pythons 3.x to build as +universal on Leopard (ppc+ppc64). I don't know if I should submit a PR though, since the fix will either impact everyone or make Portfile unnecessarily complex.

On a positive note, I got rid of a large chunk of universal voodoo (which way anyway broken) in the Portfile. However, my fix requires muniversal Portgroup. (Anticipating a question here: no, just adding muniversal to the existing Portfiles does not work.) I tried for a long time to come up with a patch to fix universal builds, an approach that worked for python27 (not committed btw yet), however even though I was able to build Pythons as +universal, packages failed to install: ​https://trac.macports.org/ticket/64916 So eventually I gave up on that, and fixed an error due to which muniversal failed in their case instead.

Since I have no idea re status of universal builds outside of PPC and general desirability of switching to muniversal, I am asking first. For PPC things finally moved forward: 36-111:files svacchanda$ port -v installed | grep python

Dependencies build as +universal, even the horrible gobject-introspection (though an older version which did not yet switch to handicapped meson).
