If you upgrade an existing build tree to use the Poky Dunfell 3.1.6 release, you are likely to see a lot of pseudo aborts. This is because commit e3cab68b in poky (commit 8c1084f3 in meta-yocto) was not backported to meta-poky. Due to this, OELAYOUT_ABI remains at 12, and thus the sanity test in sanity.bbclass that should prevent an existing tmp directory from being used does not trigger.
Can you backport this change to get poky back to a working state?
