BTW: I just got interesting question about egl_gallium:

libEGL warning: Could not open driver /usr/lib/egl/egl_gallium.so
(libLLVM-3.3.so: cannot open shared object file: No such file or
directory)
Could not initialize egl display

EGL error

-rwxr-xr-x    1 root     root       10.1K Aug 19 14:02 libprofile_rt.so

I don't know yet why it worked in my tests when I was updating mesa and
llvm, but it's true that we need to make sure that mesa finds
libLLVM-3.3.so in versioned subdirectory in runtime.
