Consequently, it's possible to install multiple flavor on the same target. This patch breaks fftw quad precision into a new package and: - makes BR2_PACKAGE_FFTW_PRECISION_QUAD select BR2_PACKAGE_FFTW_QUAD to keep compatibility with packages that use BR2_PACKAGE_FFTW_PRECISION_QUAD. This option will be removed in a follow-up commit; - makes fftw depend on fftw-quad when this package is enabled.
