    Work around broken mingw cross-compilation

    See upstream issues:
    https://bugreports.qt.io/browse/QTBUG-63637
    https://bugreports.qt.io/browse/QTBUG-63659
    https://codereview.qt-project.org/q/8bebded9

    We should be able to drop this once we are building qt 5.10.1 or later.

    Added in #12971.
