You can just drop this line (it will simplify the resulting Makefile a
bit). Also note the typo FALGS vs. FLAGS.

Please replace @top_srcdir@ with $(top_builddir): a library is never
built in the source tree. If you are inside src/ you can just write
libstream_la_LIBADD= vis/libstreamvis.la

Likewise, please replace @top_srcdir@ with $(top_builddir).
Relinking due to updated libstream.la should work then.

Ah, if you 'make' from the unittests dir (as opposed to from the
toplevel dir) then you can put something like this in
unittests/Makefile.am:
$(top_builddir)/src/libstream.la:
cd $(top_builddir)/src && $(MAKE) $(AM_MAKEFLAGS) libstream.la
.PHONY: $(top_builddir)/src/libstream.la
Note that this will make the build a bit less efficient though, as you
effectively traverse parts of the tree twice, if you run 'make' from the
toplevel build tree.
Later on, you may want to look into nonrecursive builds (see 'info
Automake Alternative').
BTW, this is all really Automake specific.
Cheers,
Ralf
