It seems Guix helped a Qt developer reproduce the bug and now there's a
proper fix:

https://bugreports.qt.io/browse/QTBUG-45205  (see bottom comment)

I will try those patches out; should have results by tomorrow.

For clarity, could you make it a separate phase before the ‘configure’
phase, and also augment the comment to mention that we do the
monkey-patching here rather than using the bundled copy so we can still
use our own headers and DSO (what Mark explained)?

OK to push with this change, thanks a lot!

The patches worked fine, and I saw nothing controversial about them so I
pushed the fix to core-updates.

I pushed another patch now, which uses the proper fix provided by the Qt
maintainers; sorry for making you go through the trouble to review
this. :-)
