Interestingly, if I run the same ./scripts/feeds update immediately afterwards, the error does not materialise. Looks like "make prereq" gets somehow run in between (via prepare-tmpinfo ???).

Looks like the scripts use the new "mkhash" even in the initial feed update phase without checking if that yet exists. Or without running "make prereq" in advance.
