OK, I was using rpm (the default), but now switched to ipk. That results
in a different error in meta/lib/oe/sdk.py:55, where do_populate() tries
to link ld.so.cache into a non-existent directory.
I have attempted a fix with the attached patch.

With that, things now appear to be working. (I think things should also
work with 'rpm' as package backend, though, right ? Should I file a bug
report somewhere to put that on record ?)

Thanks,
