Gwenhael Goavec-Merou fca8b60f86 package/fftw: break fftw-single into a dedicated package
fftw's library name depends on the precision option. Consequently,
it's possible to install multiple flavor on the same target.

This patch breaks fftw single precision into a new package and:

- makes BR2_PACKAGE_FFTW_PRECISION_SINGLE select
  BR2_PACKAGE_FFTW_SINGLE to keep compatibility with packages that use
  BR2_PACKAGE_FFTW_PRECISION_SINGLE. This option will be removed in a
  follow-up commit;

- removes the BR2_PACKAGE_FFTW_USE_SSE and BR2_PACKAGE_FFTW_USE_NEON
  otpions since they are only used for single precision. The
  corresponding CPU-capability options are directly handled in
  the fftw-single package;

- makes fftw depend on fftw-single when this package is enabled.

[Yann/Thomas:
 - Force --disable-single in FFTW_CONF_OPTS, just for the sake of
   clarity (fftw is no longer going to build the single variant)
 - Use FFTW_SINGLE_DL_SUBDIR to avoid downloading fftw multiple times
 - Minor reformatting tweaks in fftw-single.mk
 - Do not deprecate BR2_PACKAGE_FFTW_PRECISION_SINGLE and instead make
   it select BR2_PACKAGE_FFTW_SINGLE, so that packages using
   BR2_PACKAGE_FFTW_PRECISION_SINGLE continue to work.]

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
