Details:

If I try to build Octave with IDA 2.8.1 and KLU enabled I get a failure from
__ode15__.cc.

This is because the configuration tests for SUNDIALS need to be updated to IDA
2.9.0. 

When I wrote these tests it was enough to test for IDAKLU function in ida.h in
order to test both that IDA had been new enough and that it had been
configured with KLU enabled.

In IDA 2.9.0 there are some new functions for sparse matrices, which are
already used in __ode15__ [1]

In order to fix this, we should test for function IDAKLU, checking whether KLU
has been enabled and test a new function, for instance SparseSetMatToZero,
checking if the user has the new version of IDA installed.

What is the most straightforward way to do so in a configuration test?
