Sound support for NetBSD through "Linux emulation" support:

* config.in (HAVE_SOUNDCARD_H): Undef.
(HAVE_SOUND): Define if HAVE_SOUNDCARD_H.
* Makefile.in (LIBSOUND): New variable.
(LIBES): Include it.
* sound.c [HAVE_SOUNDCARD_H]: Include <sys/ioctl.h> and <soundcard.h>.
(DEFAULT_SOUND_DEVICE): Define to "/dev/dsp" if not defined elsewhere.
(vox_open): Use DEFAULT_SOUND_DEVICE.
* s/netbsd.h (DEFAULT_SOUND_DEVICE): Define to /dev/audio.
