qt4-build-multilib.eclass: explicitly build with -std=gnu++98 While some of the Qt4 packages build correctly with -std=gnu++14, others rely upon std::tr1 and other renamed library items. Because most of these issues have been resolved upstream in Qt5, the easiest solution is to ensure Qt4 is always built with -std=gnu++98.
