This is a workaround for QTBUG-21224.
For v8 we want to use QT_ARCH as the primary variable for
detecting the target platform. Unfortunately, QT_ARCH isn't
set when v8.pro is parsed using fromfile() from within
another .pro file (namely src/src.pro).
qt_config seems to be the bare minimum that's needed to get
qconfig.pri (which sets QT_ARCH and friends) loaded.
