Recent hilarity (from the same user, no less!)
- Package failed to build because `QtCore/qsystemdetection.h` was missing. Turns out the user didn't want anything related to systemd on his system, so he was removing anything that matched *systemd*.
- User wanted to be able to build Xorg with GLX support but *not* DRI, because it would save 0.4 MiB (12.4 MiB on-disk vs 12.4 MiB), and somehow this configuration was supposed to play Steam games.
