On the computers of Zahra Sharbaf and Hamed Altafi, we noticed that SExtractor's build was complaining about not having a single-precision FFTW library! This was confusing because it was being installed with no problem on other systems so far.

After checking on my own computer (with `ldd .local/bin/sex'), I noticed that it was actually building with the single precision FFTW library (libfftw3f) of my host system (in `/usr/lib'), not the pipeline's build.

After inspecting ArchLinux's build of FFTW, I noticed that they are using the `--enable-float' configure option, not `--enable-single' that we are using. In the output of `./configure --help', it says these two are the same, so we were using the latter. However, after using the former, we now have `libfftw3f' in the pipeline and so SExtractor links with it.

I am now busy finalizing the fix now.
