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.
