Thanks for this work! To me this feels like a better solution, even
though it's annoying to maintain such a local patch. I assume there's
pretty much zero chance to get this merged by upstream Chromium, and
then back into the qt5webengine code anyway.

The CPU type is encoded into the compiler wrapper. So it's really only
the optimization/debug flags that you will be missing.
