Hey,
thanks for all your help. I guess it's fine now.
If someone wants to reproduce my setup, I published the exact steps here:
https://forum.openwrt.org/t/running-vanilla-kernel-on-banana-pi-r64/145351

I still wonder why my initial try using the OpenWrt build-environment 
together with the 6.1 kernel failed.

Bests
Nick
