[PATCH] wineoss: Fix the -lossaudio check.

[Francois Gouget]

Only check for libossaudio if compiling wineossi.drv and the headers
are recent enough.
Disable building wineoss.drv if the library is missing.
Only link with libossaudio when needed.

Linking with libossaudio is troublesome on NetBSD but what makes matters 
worse is that Wine links every library with it. Zerous fixed the build 
system so only wineoss.drv is linked with it.
 
But then I noticed that configure checks for libossaudio even if given 
--without-oss. So I took his patch and tweaked it some more.
