The DRI (not X) drivers *_dri.so used to be linked against libGL, but
they no longer are due to AIGLX, where the X server dlopens them, and
their references must be resolved in the X server, not libGL.

It may be possible to work around this in libGL, but it might be a good
idea for SDL to dlopen it with RTLD_GLOBAL nevertheless.
