I haven´t followed through the logic exactly to know where it falls apart, but I know I always run into issues when I use -j instead of JFLAG for specifying -j.

Maybe the j*j thing happened with fmake, I vaguely remember that. With
bmake the -j value propagates in some magic way so that even though
you're building arches in parallel, the total number of jobs is the -j
value (which you can see pretty clearly in top, after a few minutes the
load averages pretty much lock onto the -j value plus some fraction).
I've never had any problems with objdir stuff building all the arches in
parallel at any value for -j (but I typically never use numbers higher
than 14 unless I'm testing build stuff).
