How did you build PyQt5 on ppc64le?

Hey folks,

regarding to this page and my own tests it seems that you where able to
build PyQt5 on ppc64le architecture.

This feels like magic to me because even the upstream maintainers are
not able to do it. See https://github.com/PyQt5/PyQt/issues/150

I also asked at upstream how to do it:
https://www.riverbankcomputing.com/pipermail/pyqt/2022-September/044898.html

Errors like this occur
"AttributeError: module 'sipbuild.api' has no attribute
'prepare_metadata_for_build_wheel' "

It would be great and really helpful if you could provide some
informations and hints about how did you build the python3-pyqt5
package for ppc64le architecture.

Kind
Christian
