When you link an application with your libocicpp.la with libtool later
in the build process, it will automatically add -lcore4 and -lnlsrt3
to the link line.

Alternatively you can arrange for shared version of these libraries to
be available at the time you ask libtool to make your library depend
on them.  Many hosts do not allow a shared library to depend on a
static library, which is why you see the warnings above.
