latest finufft does not build on cori gpu
We need the latest finufft to compare cmtip and spinifel on Cori gpu.
Adding @jpblaschke's email message to summarize current status: finufft needs the single-precision fftw3 symbols -- which we don't build on cori gpu. We have a few options here: i) I have a PR to disable single-precision finufft symbols: https://github.com/flatironinstitute/finufft/pull/179/files (there is some discussion, so this lost momentum, but we should probably pick this up again); ii) build your own fftw3; iii) build the single-precision symbols in our cori-gpu fftw3 module.
