whether of not to automatically #define EXCLUDE_AUDIO; MSS is a real
audio device and we should not #define EXCLUDE_AUDIO if we have one.
(And I want it because it's the only mixer-capable audio driver that I
can use with my crummy Packard Bell (nee Aztech) audio board.)
This fixes the very confusing condition where having all of this:
mss0 at 0x530 irq 10 drq 1 on isa
gus0: <MS Sound System (CS4231)>
opl0 at 0x388 on isa
opl0: <Yamaha OPL-3 FM>
mpu0 at 0x300 irq 9 drq 0 on isa
mpu0: <MPU-401 MIDI Interface 0.0 >
will still give you this:
% cat /dev/sndstat
SoundCard Error: The soundcard system has not been configured
Also remove an unnecessary newline in the printf() message for the
'gus0' device shown above so that we don't wind up printing a blank
line between mss0 and gus0.
