Found it myself - the variable MACHINE_EXTRA_RRECOMMENDS was referenced
by my core task, something like this:
   RRECOMMENDS_task-my-distro-boot = "\
     ${MACHINE_EXTRA_RRECOMMENDS} \
   "
I hadn't rebuilt that task, so the reference remained.  I'm still not
sure why it didn't end up in the .dot graphs though.
