Since the sstate-cache used in CI is hosted on a NFS server, this change will allow measuring its latency. Performing an initial build at each subbuild step using only the bitbake setscene tasks, will allow us to measure the time of that task. Which basically consists of executing all the task that can be accelerated using the stored sstate-cache. These tasks make exhaustive use of the NFS filesystem to acquire the sstate-cache artifacts. With this change, it will be easy to distinguish between the time required to acquire and unpack the sstate-cache artifacts and the time spent on the build itself.

Initial tests suggest that the NFS latency is negligible:
