Comment # 4 on bug 55510 from maxijac@free.fr

I had no x86 libtxc_dxtn, so I compiled it for x86 but no change, shaders still
seem to fail at compiling.

I tried installing lib32-libtxc_dxtn from AUR (I use Arch) and still bad
rendering. How can I test libtxc is installed properly for x86 ?

And I do have the --enable-texture-float configure option.
