Testing: compile-tested all the permutations of enabling/disabling
fftw-single, fftw-double, and fftw-long-double on an aarch64 build (so
no fftw-quad available)
Thanks for your work on this patch series, Gwenhael! I ran into this
awhile back, where I noticed I could only select one FFTW build, and I
had some issues with liquid-dsp depending on which one was selected.
I decided to just pick the one option that worked even though I would
have liked to have another available. I was too busy at the time to
spend time trying to fix it.
