[Buildroot] [PATCH v3 16/17] package/fftw: remove as regular package

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, Gwenha?l, All,

On 2018-12-31 14:30 +0100, Thomas Petazzoni spake thusly:
> fftw is no longer a package: only fftw-single, fftw-double,
> fftw-long-double and fftw-quad are. fftw.mk only contains some common
> definitions that are used by the different fftw variants.
> 
> The old BR2_PACKAGE_FFTW_PRECISION_* options, which are no longer used
> anywhere, are moved to Config.in.legacy.

A review of that one even if the previoius are not still reviewed, so
that I don;t forget what I noticed...

So, basically, enabling the fftw package no longer ensures there is at
least one variant to build.

This basically means that a defconfig that relied on the default flavour
to be enabled (double) now breaks.

What about:

    config BR2_PACKAGE_FFTW
        bool "fftw"
        select BR2_PACKAGE_FFTW_DOUBLE if !BR2_PACKAGE_FFTW_SINGLE \
                                       && !BR2_PACKAGE_FFTW_LONG_DOUBLE \
                                       && !BR2_PACKAGE_FFTW_QUAD

Or something to ensure there is at least one variant enabled (and the
same as the default precviouslty was).

Yann E. MORIN.
