Full rebuild fails for mingw-w64-qtwebkit for x86_64

[emmenlau]

The build fails relatively early on, with error:

Generating MOC compilation DatabaseProcess_autogen/moc_compilation.cpp
Scanning dependencies of target tst_qmltests_WebView_autogen
Could not open D:/Temp/mingw-w64-qtwebkit/src/build-x86_64-w64-mingw32-debug/DerivedSources/ForwardingHeaders/WebCore/PopupMenu.h. at D:/Temp/mingw-w64-qtwebkit/src/qtwebkit-5.212.0-alpha/Source/WebKit2/Scripts/generate-forwarding-headers.pl line 120, <EXISTING_HEADER> line 1.

make[1]: *** [CMakeFiles/Makefile2:2660: Source/WebKit2/CMakeFiles/WebKit2-forwarding-headers.dir/all] Error 2

I think the paths are not too long, the full path is "just" 115 characters.
