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

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.
