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.]

The check-package script when ran gives warnings on text wrapping
on all of these Config files. This patch cleans up all warnings
related to the text wrapping for the Config files starting with
the letter f in the package directory.
The appropriate indentation is: <tab><2 spaces><62 chars>
See http://nightly.buildroot.org/#writing-rules-config-in for more

Use FFTW_CFLAGS as intermediate variable, since we're going to need it
in a later patch (about NEON optimisations).

fftw has options to select compile precision between single, long-double
and quad. These options are exclusives. This patch adds choice to select
precision option.
