Automated build process (buster)

Made below commit on ONE branch:

Regarding Fail #1, I followed these steps, without installing the driver of course, simply downloaded, extracted and installed the xinput-calibrator deb file and run the calibration tool producing these:

Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "ADS7846 Touchscreen"
        Option  "Calibration"   "254 3910 3716 1476"
        Option  "SwapAxes"      "1"
        Option "InvertX" "1"
        Option "InvertY" "1"

and copied to /etc/X11/xorg.conf.d/99-calibration.conf (replacing old entry) and it seems to work fine now. I doubt this will work on both you and me. Not sure what to make of it if you tested on the crowdfunding campaign LCD which is what I (only) have here too.
