[Buildroot] [PATCH 0/7 v7] package/fftw: add a bunch of optimisations (branch yem/fftw)

[Yann E. MORIN]

Hello All!

This series aggregates misc optimisation patches for out fftw package,
based on work by Gwenhael and Guillaume.

Thanks to both for their previous work! :-)


Changes v6 -> v7:
  - re-order patches
  - reword promopts ('none' -> 'double')
  - fix SSE2 (not available for long-double, only 'double')  (Gwenhael)
  - force use of NEON when available, not when suer-selected  (Thomas)
  - generate a single library with threads

Changes v5 -> v6:
  - architecture optimisations are not available for all precisions
    (Thomas, Gwenhael)

Changes v4 -> v5:
  - use --disable-XXX in first patch
  - add architecture optimisations for x86 and ARM
  - add other optimisations (threads, openMP, fast maths)


Regards,
Yann E. MORIN.
