According to https://wiki.debian.org/ArchitectureSpecificsMemo#armhf , NEON instructions are not guaranteed on armhf platform. However, your debian/rules explicitly enabled NEON support in armhf build. This should be a violation to architecture baseline. Please consider fixing this issue. Ubuntu is providing an example patch for it, and it can be used as a reference (patch attached).
fftw3 uses runtime feature detection, neon instructions are only used when the hardware supports it.
