If I'm correct in the belief that jacobi() finds eigenvalues and
eigenvectors, then this should already be provided by eigen(), which
is just a wrapper around G_tqli and G_tred2.

It's hard to get the logic exactly right. And configure already
provides a warning (which could be made into an error, but there are
only 3 programs which need fft()).
