Doh! My apologies. As you noticed, about one time out of three I seem
to type LIMIT instead of LEVEL, and they're visually similar enough
that I don't notice even after looking at the file repeatedly.

I apparently tested

   make BR2_JLIMIT=3
   
     instead of
     
   make BR2_JLEVEL=3 

Sorry for the noise.
