madplay: add patch to switch to the new ALSA API
madplay was failing to build with errors such as : audio_alsa.o: In function `config': audio_alsa.c:(.text+0x200): undefined reference to `snd_pcm_hw_params_set_rate_near@ALSA_0.9' audio_alsa.c:(.text+0x25c): undefined reference to `snd_pcm_hw_params_set_buffer_time_near@ALSA_0.9' audio_alsa.c:(.text+0x284): undefined reference to `snd_pcm_hw_params_get_buffer_size@ALSA_0.9' audio_alsa.c:(.text+0x2a4): undefined reference to `snd_pcm_hw_params_set_period_time_near@ALSA_0.9' audio_alsa.c:(.text+0x2d4): undefined reference to `snd_pcm_hw_params_get_period_size@ALSA_0.9' The ALSA library uses symbol versioning by default, to handle ABI changes. However, since uClibc doesn't seem to support symbol versioning, we disable this when building the ALSA library by passing --without-versioned. However, madplay relies on the old ALSA ABI, so even without symbol versioning, references to versioned symbols are generated (functions with the same name, but different API, exist in the old and new API). The easiest solution is to switch madplay to the new API. This is done thanks to a patch written by Micha Nelissen <micha@neli.hopto.org> and available at http://article.gmane.org/gmane.comp.audio.mad.devel/729.
