Consequently, it's possible to install multiple flavor on the same target. This patch breaks fftw long double precision into a new package and: - makes BR2_PACKAGE_FFTW_PRECISION_LONG_DOUBLE select BR2_PACKAGE_FFTW_LONG_DOUBLE to keep compatibility with packages that use BR2_PACKAGE_FFTW_PRECISION_LONG_DOUBLE. This option will be removed in a follow-up commit; - makes fftw depend on fftw-long-double when this package is enabled. Signed-off-by: Gwenhael Goavec-Merou <gwenhael.goavec-merou@trabucayre.com> [Yann/Thomas: - Force --disable-long-double in FFTW_CONF_OPTS, just for the sake of clarity (fftw is no longer going to build the long double variant) - Use FFTW_LONG_DOUBLE_DL_SUBDIR to avoid downloading fftw multiple times - Minor reformatting tweaks in fftw-long-double.mk - Do not deprecate BR2_PACKAGE_FFTW_PRECISION_LONG_DOUBLE and instead make it select BR2_PACKAGE_FFTW_LONG_DOUBLE, so that packages using BR2_PACKAGE_FFTW_PRECISION_LONG_DOUBLE continue to work.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Tested-by: "Yann E.
