Subject: [PATCH] fftw: 3.3.4 -> 05-06-2016

There has not been a release since 2014, but at least one important bug
has been fixed:
https://github.com/FFTW/fftw3/issues/16

The submitter of the bug, @x-42, has advised me to upgrade our distro,
as the fftw devs are very conservative so this is not bleeding edge code.
