[Buildroot] [PATCH v4 17/17] package/liquid-dsp: drop support for fftw-double and fftw-long-double

liquid-dsp has the following code:
#if HAVE_FFTW3_H && !defined LIQUID_FFTOVERRIDE
#   include <fftw3.h>
#   define FFT_PLAN             fftwf_plan
#   define FFT_CREATE_PLAN      fftwf_plan_dft_1d
#   define FFT_DESTROY_PLAN     fftwf_destroy_plan
#   define FFT_EXECUTE          fftwf_execute
#   define FFT_DIR_FORWARD      FFTW_FORWARD
#   define FFT_DIR_BACKWARD     FFTW_BACKWARD
#   define FFT_METHOD           FFTW_ESTIMATE
#else
#   define FFT_PLAN             fftplan
#   define FFT_CREATE_PLAN      fft_create_plan
#   define FFT_DESTROY_PLAN     fft_destroy_plan
#   define FFT_EXECUTE          fft_execute
#   define FFT_DIR_FORWARD      LIQUID_FFT_FORWARD
#   define FFT_DIR_BACKWARD     LIQUID_FFT_BACKWARD
#   define FFT_METHOD           0
#endif

So, if it uses the external fftw library, it can only use the fftwf
variant, i.e the fftw-single variant. Otherwise, it uses its internal
FFT library.

There is no way for liquid-dsp to use fftw-double or fftw-long-double.
