fist obvious thing is that your code a 1 day older than my snapshot, but the 
commits in between seem absolutely irrelevant.
One difference: you build your own image, I used the prebuilt from 
downloads.openwrt.org.
Just defaulted my board again with firstboot and had the issue again...

Digging further I found installing online pulled librt in. Restarting from 
scratch ...
Downloading librt and wall via wget and running `opkg *.ipk` - packages have 
been installed successfully.

So the issue is obviously caused by resolving the dependencies which triggers 
the faulty message:

Collected errors:
 * pkg_hash_fetch_best_installation_candidate: Packages for wall found, but 
incompatible with the architectures configured"

Previous opkg-version gave a correct indication about missing dependencies.

@Hannu: can you reproduce the issue by installing a package that is 
definitively missing a dependency?
