For release tarballs we try our best to make sure WebKitGTK (and also WPE)
build correctly when using “-DENABLE_UNIFIED_BUILDS=OFF”, but if you try to
build trunk it is quite likely that it will fail. Every now and then we land
fixes in trunk to keep non-unified builds working, so if you locate one of
those commits, the build is more likely to succeed (still, YMMV with trunk!)

True, I forgot about this in my previous message :)
