This looks fine to me.

Automake just outputs rules to build the libj.la, and these
probably haven't changed a lot.  Libtool is called at make-time
to build libj.la; this can cause static or shared libraries to
be built as a side effect, depending on the configuration of
libtool.  So for such a problem, you should probably look how
libtool is setup.

I'm wondering whether you might be thinking that shared
libraries are not built simply because you cannot see them.
Libtool builds such libraries in a secret place.  You should
only refer to libj.la in your Makefile and let libtool do the
magic.
