[PATCH v2] wineoss: Fix the -lossaudio check.

[Francois Gouget]

Only check for libossaudio if compiling wineoss.drv and the headers
are recent enough.
Also only wineoss.drv needs to be linked with libossaudio so put the 
link options in OSS4_LIBS.
But do not disable building wineoss.drv if the library is missing since
it is not needed for wineoss.drv on Linux.
