Bug#630666: multiarch breaks webgl in chromium

[John Smith <extromium@gmail.com>]

Source: mesa
Version: 7.10.2-4

My video card is a nVidia one.
Webgl in chromium run smoothly with mesa <= 7.10.2-3.

After upgrading to 7.10.2-4 and 7.10.3-1, chromium just complain that
it do not support webgl.
However, chrome://gpu-internals/ still show that everything is
"Hardware accelerated".
I had tried to symlink so files to /usr/lib, but the error remains.

I dropped all multiarch diffs and rebuild mesa, webgl works again with
mesa 7.10.3.

I think chromium uses dlopen() tricks, but I have no idea why symlinks
do not work for it.
