Comment (by ryandesign):
`std::variant` seems to require C++17. The build seems to be requesting
C++11 mode, so naturally this will fail:
{{{
:info:build libtool: compile: /usr/bin/clang++ -std=gnu++11 -std=c++17
-std=gnu++11 -DHAVE_CONFIG_H -I. -I../.. -I../../include

}}}
Essentially the same problem was reported for ixion-0.17 in #70373.
