Several packages got renamed/updated, libgcrypt was apparently installed
by default previously.
Since most libraries changed we have to completely rebuild all the tools
installed in the root image. We currently don't provide a clean target in
the recipes, and even if we did we'd have to track which base image we
last built for. It's easier to just use a different build directory for
each base image, at the cost of some additional disk space (if not manually
cleaned). However, that's also the case when updating kernel or
software versions.
