alsa-utils: make fftw an optional dependency for alsabat
The BR2_PACKAGE_ALSA_UTILS_BAT option currently selects BR2_PACKAGE_FFTW. However, it turns out that fftw is not a mandatory dependency to build alsabat, just an optional dependency. This commit therefore turns this dependency into an optional one. However, it is not just FFTW that is necessary, but the simple precision version of FFTW, so the optional dependency takes this into account. We take this opportunity to extend the Config.in help text for BR2_PACKAGE_ALSA_UTILS_BAT.
