I am having a hell of a time trying to figure out what I can skip if I want to build QtLocation and QtPurchasing for components qt and pyqt5. The process of elimination is time-consuming for an entire sysroot :)

Write a .pro file that contains the QT values for the modules you explicitly want and look at the generated Makefile to see what libraries are actually going to be used, then skip everything else.
