If a recipe is named such that it matches something already in OVERRIDES (such as when PN happens to be the same as MACHINE or DISTRO), it can have unexpected consequences. Assignments such as FILES_${PN} = "xyz" effectively turn into FILES = "xyz". We should therefore show a warning if ${PN} is in OVERRIDES.

Verified. Warning is shown when PN matches something in OVERRIDES.
