[patch] SqueakVM doesn't build on OSS systems

>
>  Hello!
>
> First, you can't build SqueakVM on NetBSD because it links to
> non-existing library (OSS isn't ALSA).
>
> Second, audio devices are /dev/audio* and /dev/sound* rather than /dev/dsp*.
>
> Third, sometimes default devices are /dev/audio1 and /dev/sound1.
> E.g. on my rather modern (2008) laptop.
>
> Here're patches I use, usage example:
> squeak -vm-sound-OSS -playback /dev/audio1 Squeak4.0-basic.image
>
>
> Use proper OSS library.
> Use proper audio device.
