Failures from __ode15__ in 'make check'

Carlo,

I'm getting 50+ failures from __ode15__.cc when running 'make check'.  They
are all of this type

***** test  # Mass option as matrix
 opt = odeset ("Mass", eye (2,2), "MStateDependence", "none");
 sol = ode15s (@fpol, [0 2], [2 0], opt);
 assert ([sol.x(end), sol.y(end,:)], [2, fref], 3e-3);
!!!!! test failed
__ode15__: support for sundials_ida, sundials_nvecserial was unavailable or
disabled when Octave was built

It appears that a common declaration, like HAVE_SUNDIALS, needs to be
declared by configure so that  these tests are only run when there is
support for them.  The correstponding tests can then begin with

%!testif HAVE_SUNDIALS
