Hi Andreas, if I look at your requirements, take a look at the PinePhone and start with modifying the Ubuntu Touch image provided by Pine. It is likely that you can install GNUstep almost the same way as you do on any other Ubuntu PC.
I have a developer device which almost runs a stock Linux kernel and it did simply start a 32 bit Debian Jessie root-file system (although it is an aarch64 processor) with X11 and touch out of the box. So I could also install the mySTEP packages without any efforts. But I haven't had time to investigate or make anything else (GPS, LTE, charging, WiFi, Bluetooth, Audio) really working. Or switch everything to a newer Debian release (libjpeg and some others are not easily interchangeable between Jessie, Stretch, Buster etc.). Well, it is not really rugged but cheap enough to replace a broken unit...
