Bug#876033: primusrun doesn't find libGL.so.1

[devfra]

Hello

The new version of primus have arrived today in Testing, everything works but 
there is still a problem with the 32 bit version of LibGL.so.1.

I have a couple of 32-bit only applications that I run with wine, they give me 
the following message:

primus: fatal: failed to load any of the libraries: /usr/lib/x86_64-linux-gnu/
nvidia/libGL.so.1:/usr/lib/i386-linux-gnu/nvidia/libGL.so.1:/usr/lib/nvidia/
libGL.so.1
/usr/lib/x86_64-linux-gnu/nvidia/libGL.so.1: wrong ELF class: ELFCLASS64
/usr/lib/i386-linux-gnu/nvidia/libGL.so.1: cannot open shared object file: No 
such file or directory
/usr/lib/nvidia/libGL.so.1: cannot open shared object file: No such file or 
directory

Other 64 bit applications work with bumblebee as expected.
