Summary: Build fails on chromium configuration. Even without gnome and gnome-keyring useflags. Previously could build without GTK3 being present on system.

Yes, we've recently changed things in Chromium so that we build in support for gtk3 by default (when you build everything). Chrome itself does not require it. The `use_gtk3` flag at the moment is false and determines whether or not Chrome will link against it. There is not currently a way to disable the compile-time requirement, unless you want to build with ozone instead. We can add one but I wouldn't necessarily want to do that without understanding whether we can just add the compile-time headers instead. (Obviously, compile-time and run-time dependencies are two different things).
