It's highly plausible that exactly that happened: I forgot `make
oldconfig' during the first build and assumed (ha!) that `make dep'
would fix everything up OK so that a config change would trigger
rebuilds appropriately. Possibly this was a foolish assumption and a
`make dep clean' was necessary.

OK.

That's my conclusion too. I'll try rebuilding from scratch tomorrow
evening and see if that works.

(Oops.)
