 Or, backport QT 5.12 to OS X 10.11. I did this for QT 5.9 on Mavericks,
 and it was actually _way_ easier than I expected it to be! I have a patch
 here https://trac.macports.org/ticket/62964; it won't help with this
 ticket directly, but it demonstrates feasibility (and I do want to try
 with later versions when I have a free weekend).
