From: Gwenhael Goavec-Merou <gwenhael.goavec-merou@trabucayre.com>

fftw's library name depends on the precision option. Consequently,
it's possible to install multiple flavor on the same target.

This patch split current fftw in 5 part:
- 1 to provide common variables
- 4 to provide specificities for each precision.

This patch suppress hidden BR2_PACKAGE_FFTW_USE_xx variables and directly use
corresponding options in specifics .mk.

Based on http://lists.busybox.net/pipermail/buildroot/2016-August/170116.html

 This is a huge change, and IIUC all patches should in fact be squashed since
this change breaks all packages depending on fftw...

 Maybe a more gradual approach would be to break out the individual packages one
by one. E.g. start with adding the fftw-single package independently of the
rest, then convert other packages to depend on fftw-single instead of fftw, then
remove BR2_PACKAGE_FFTW_PRECISION_SINGLE.

 Finally, you forgot legacy handling. When you remove
BR2_PACKAGE_FFTW_PRECISION_SINGLE, there should be an entry added to
Config.in.legacy that select BR2_PACKAGE_FFTW_SINGLE. Or you have to call the
package fftw-precision-single, of course.

 This doesn't work: the package is actually called 'fftw-double', so it will use
variables FFTW_DOUBLE_VERSION etc., not FFTW_PRECISION_DOUBLE_VERSION. I don't
know how you tested this, but it can't possibly work...

What about another approach:

  - add a new packages for each of fftw-{single,double,long-double,quad},
  - make fftw depends on all of those that are actually enabled, but
    fftw by itself does nothing,
  - if fftw is enabled, ensure that at least one variant is enabled.

Thus, packages that need any flavour of fftw can just select/depend on
fftw, while those that require specific variant would select/depend what
they need.

Regards,
Yann E. MORIN.
