[ubuntu-x] [libgl1-mesa-dev] mesa libGL.so link should not put in /usr/lib/x86_64-linux-gnu

[kajo keji]

Thank you Michael for your answer
As for you, my libGL.so.1 link to the proprietary lib :
        libGL.so.1 (libc6,x86-64) => /usr/lib/fglrx/libGL.so.1
        libGL.so.1 (libc6) => /usr/lib32/fglrx/libGL.so.1
        libGL.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libGL.so
        libGL.so (libc6,x86-64) => /usr/lib/fglrx/libGL.so

So libGL.so.1 seems to be used instead of libGL.so, here is the magic for
me. I am a bit lost about how shared library names are handled...
