Qt 5.10 skipped?

[Jason Liu]

Does anyone have any objections if I were to resurrect Qt 5.10? One of the
ports that I am working on crashes under certain circumstances when using
qt511, which is the newest Qt that works on macOS 10.11. The version of Qt
that was bundled with the pre-built binary distribution was Qt 5.10.
Admittedly, I am also able to compile the port using qt59, and there are no
crashes. In addition, I can also compile the port using qt513 on macOS
10.13, and there are also no crashes (qt512 also doesn't currently exist).

I'm not really sure how much Qt changes with each version. So on the one
hand, it would be nice to be able to get the port working with the same
version of Qt that it originally shipped with, but on the other hand, it
seems like overkill to bring back such a large set of ports as qt510-* just
for the sake of a single port on old versions of macOS.

What are everyone's thoughts on this?
