The usual way would be atime, so if you can remember when it was last moved
then anything that hasn't been touched since is obviously deletable.

The alternative would be to just delete it and then do a set of builds for
all your combinations that you care about, after all it's just a cache.

Also, that's not huge:

$ du -s /data/poky-master/sstate/
1.2T /data/poky-master/sstate/
