Currently cross-architecture dependencies are not possible, so there is 
nothing wine can do about this - of course it needs the 32bit GL libraries to 
run 32bit windows applications with OpenGL.
Once wine is gone multiarch, the libwine-gl-unstable:i386 dependency on the 
libgl1-mesa-glx:i386 will pull in the libgl1-mesa-dri:i386 via a recommends (a 
depends would be wrong, people could use another implementation of the 
acceleration - for example, the one from the nvidia/AMD blobs). The the issue 
will be gone.

Kind regards,
Ralf
