In addition, QtWebEngine always requires SSE2 no matter how you configure 
Qt. Chromium stopped supporting machines without SSE2 a few years ago.

There is a huge patch (from me) to allow building for non-SSE2 i686 machines 
in the Fedora qt5-qtwebengine package, but that patch is completely 
unsupported by upstream.
