+    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.
