Currently py-qt6 builds itself in the configure step, in a single
thread that takes well over two hours on a fast machine. In the
latest exopi bulk:

max_stuck=291.37/depends=17.09/show-prepare-results=5.24/patch=0.86/configure=8543.77/build=6.05/fake=17.14/package=40.79/clean=0.89

With the diff below, I could configure it in 10 minutes and build it
in ~15 minutes with -j8 on an 8-core laptop. The plist grew some .pyi
files, which I think is fine.

I don't use anything using this and don't plan to, so it's only build
tested.

If this works and is acceptable, I think we can give py-qt5 the
same treatment. Setting DPB_PROPERTIES = parallel can then be
considered separately.
