"ldd -a" exposes more libc++ consumers: libGLU (from mesa-libs), fltk and
cpptest. Each of those libraries may have their own consumers (ignoring
openvsp) linked against libc++.

Can toolchain@ suggest a better workaround? libstdc++ usage is fragile as any
dependency can bring libc++ into runtime leading to crashes. While mixing
libc++ and libstdc++ is possible by replacing libsupc++ with libcxxrt it's not
supported by any of lang/gcc* ports. libcxxrt is essentially frozen from ports
POV.

Alternatives are locking the ports to USE_GCC < 6 (if gerald is OK) or laying
on BROKEN_FreeBSD_10 deathbed.
