Here are some updates:

Building core-image-weston on hardknott succeeded. Couldn't `runqmu kvm slirp 
sdl core-image-weston` first because I got an error message about 'dri.pc' 
being missing. Debian package search told me it's part of 'mesa-commond-dev', 
so I installed it on my host machine and indeed, that runqemu command above got 
working again. Not just that, now even OpenGL acceleration with `runqmu kvm 
slirp sdl gl core-image-weston` worked, altough I didn't change anything 
OpenGL-wise. core-image-weston feels really snappy now. Great!

I got curious and reverted back to dunfell to check if the now-installed dri.pc 
made a difference, but no, it didn't. `runqemu` with `sdl` started (like it did 
before), and with `sdl gl` it still said "OpenGL support is disabled".

Ok, so then I moved on to get my own image which is on hardknott now working.

I `runqemu`d my image with 'sdl' and 'gl' and it started up fine. Weston did no 
longer start automatically so I did manually. Ran `DISPLAY=:0 glxgears` but it 
told me "couldn't open display :0". Installed 'weston-xwayland' so I'd get 
"/usr/lib/libweston-9/" but that didn't change anything.

Can't yet say if `DISPLAY=:0 glxgears` works on core-image-weston as it's still
