RFE: add a `configure.objcxx` variable

[cooljeanius (Eric Gallager)]

According to the guide, there's a configure.cxx variable, and a configure.objc variable, but it doesn't mention anything about a configure.objcxx variable. It would be useful to have such a variable. (If one already exists and I just don't know about it, then the guide should document it.)

Why would this be useful?

[ryandesign (Ryan Carsten Schmidt)]

Or: What port fails to build or has to implement a workaround because of this deficiency?

[larryv (Lawrence Velázquez)]

Out of every file in the ports tree:

% find ~/Projects/MacPorts/trunk/dports -type f -exec grep -l OBJCXX {} + | wc -l
      13

[jmroot (Joshua Root)]

And 12 of those are false positives.

[ryandesign (Ryan Carsten Schmidt)]

I see no port currently manually setting OBJCXX. But that doesn't mean no ports would benefit from it. For example, texlive-bin's build system uses it, as I reported in #39684. There would be no detriment to adding this variable to base, would there? It would make MacPorts more complete.

Replying to ryandesign@…:

I suppose not. At least there’s one port that can use it, now.

[cooljeanius (Eric Gallager)]

I was thinking of setting this in the qmake portgroup when I first created this ticket, but then I kinda forgot about it...

Cc Me!

[drkp (Dan Ports)]

Yeah, this would be nice to have for texlive-bin and potentially for future ports.
