Build broke; see https://github.com/adafruit/circuitpython/runs/1042094212?check_suite_focus=true

Approved pending a double check that this is a "real" failure, not a spurious failure. @dhalbert will verify and merge if the problem repeats on a fresh Actions build.

I've seen this failure before and don't think its a board issue.

The failure was a red herring. The re-run ran fine. Out of all the boards, just the seemingly relevant one happened to fail. Closing without applying.
