I discovered what was causing these errors - I have buildhistory
enabled for target B.  Periodically I rebuild target A from scratch
and this gives buildhistory on target B fits.  For now, I'll just
disable buildhistory...

BTW, except for the buildhistory "errors", using sstate like
this does help quite a lot.
