Comment (by eschnett):

 We should not make boilerplate changes to option lists. This is likely to
 break things. Either an option list is unused, and in this case, leaving
 it at its old state makes it easiest to update it, because then one
 doesn't have to find out which untested changes were applied. Or the
 option list is used, in which case it is working, and making changes is
 not necessary.

 In this case, FFTW_DIR is for version 2 of the FFTW library, whereas
 FFTW3_DIR is for version three. These two libraries are not compatible.
 FFTW is supported by Cactus using the old configuration mechanism (i.e.
 without using a thorn to configure it). I would either leave this in (if
 it works), or remove these definitions (under the assumption that FFTW
 version 2 is not installed on these systems any more). However, the latter
 assumption is dangerous.

 I would rather go through this machine by machine, updating those option
 lists that are used (and where people care), and moving the other option
 lists to a "retired" or "nobody looked at this in the past year"
 directory.
