There is something rotten in the state of Denmark. Here are four recent runs that failed with unexpected "cache lookup failed for type nnnn" errors:

It's notable though that all the failing machines are PPC or S/390 ... maybe big-endian related? I grepped through the buildfarm logs and determined that there are exactly zero similar failures going back as far as 2016-04-01. Now that we've had four in a week, it seems certain that this indicates a bug introduced at most a few days before Aug 9. A quick trawl through the git logs finds no obvious candidates, though.
