Since this port links to libraries compiled with GCC7 on GCC-based
architectures, add USES=compiler:c++11-lang to fix linking.

I don't see any issues with this. I have updated the patch in bug #225941 to match.
Other ports that I maintain also have USES=compiler with C++11 or C++14 which were put in place to fix builds on 10.4 due to the base clang failing. Most of these ports use opencolorio - openimageio openshadinglanguage blender
I was planning to remove these with next updates now that 10.4 is EOL, should these be kept in place to support GCC archs? See based on failed builds?
devel/godot and godot2 also have USES=compiler for the same reason but these are more standalone so expect these can be removed.
(In reply to Shane from comment #2)
Yes, those should be left, because of base GCC.
Base GCC doesn't even support C++03, let alone C++11 and newer.
It also doesn't support C11.
Please leave it as it is, unless those ports compile with GCC 4.2.
Now see PR 233888.
