Subject: [PATCH] sstate.bbclass: Add progress bars when removing from the sysroots
Precedence: list

If there are many recipes that should be cleaned out from the
sysroots, it can actually take some time. This adds a progress bar to
give a visual clue that the clean up is actually progressing.
