Here's my batch of modular qt patches. I found a couple of issues while I was making them. qtbase doesn't produce the binary lrelease so qttranslations can't be built, and qtquick, which had its last release in 5.4.2, can't be found by qtquickcontrols or qtgraphicaleffects. I didn't build qtwebengine or the ones that depended on it. When I realized 5.6.1 had been released I built all of these, minus qttools, with qtbase, in 3.25 hours, a significant decrease compared to the full bundle.
https://code.qt.io/cgit/qt/qt5.git/tree/.gitmodules?h=5.6.1 was a great cheat-sheet for what modules needed which other ones as inputs.
