I've just updated a tree to try to reproduce.
Are you sure /usr/bin/make is bmake?

I see lots of makefiles that invoke 'make' rather than ${MAKE},
so could imagine a problem if /usr/bin/make is *not* bmake.
If WITH_BMAKE is set, src/Makefile will build bmake and use it as 
${MAKEPATH}/make, but the PATH is not tweaked to ensure that that 'make'
is found, so /usr/bin/make would get used.
Also of course one must do a parallel build, to trigger that error about
-J.

Anyway I started a parallel buildworld with /usr/bin/make not bmake 
and the bug mentioned above not fixed to see if that causes the error
you see...
