ALSA and libasound.so

The only supported interface to the ALSA 5 drivers is through libasound.so. Direct use of ioctl() commands isn't supported because of the requirements of the ALSA API. It uses ioctl() commands in ways that are illegal in the QNX Neutrino OS (e.g. passing a structure that contains a pointer through an ioctl()).

We include the asound library only as a shared library (libasound.so), and not as a static library.
