`static-libstdc++` works with both libc++ and libstdc++ (confusingly), the choice of C++ library is controlled by `-stdlib=` flag. This branch is used to check that libFuzzer can be used with statically linked C++ library (i.e. to ensure that the symbols from the internalized C++ library are properly hidden and localized to don't cause collision).
