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. Signed-off-by: Gwenhael Goavec-Merou <gwenhael.goavec-merou@trabucayre.com> [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.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Reviewed-by: "Yann E.
