bitbake: runqueue: Add output for -S option for listing the changepoints compared with an sstate cache
Its useful to understand where the delta starts against an existing sstate cache for a given target. Adding this to the output of the -S option seems like a natural fit. We use the hashvalidate function to figure this out and assume it can find siginfo files for more than just the setscene tasks. (Bitbake rev: c18b8450640ebfd55a2b35b112959f9ea3e0a700) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
