Title:
  fftw3 neon support config fixups for armv8

Status in Linaro AArch64 cross-distro work:
  New
Status in “fftw3” package in Ubuntu:

Status in “fftw3” package in Debian:
  New

Bug description:
  fftw3 (FFT library) has SIMD support for various architectures. This
  was naively enabled in 3.3.3-6 debian package in a way that didn't
  work as it assumed that -mfpu=neon was neeed as a compiler option and
  that __ARM_NEON__ would be defined if neon available. Neither of these
  are true for armv8/aarch64-linux-gnu-gcc so different configurey
  handling is needed.

  Patch attached.
