Bug#640499: libxvmc: please add multiarch support

[Nicolas Le Cam <niko.lecam@gmail.com>]

Dear Maintainer,

Now that latest 304.43-1 nvidia binary drivers have been migrated to
testing, it is adverted to switch from *nvidia*-ia32 packages to
multiarch ones using :

dpkg --add-architecture i386
apt-get update
apt-get install libgl1-nvidia-glx:i386
apt-get install nvidia-vdpau-driver:i386
apt-get install libcuda1:i386
apt-get install nvidia-opencl-icd:i386

Unfortunately this bug is blocking the first install command.

sudo apt-get install libgl1-nvidia-glx:i386
