r600_dri.so fails to load because of the game's copy of libgcc_s.so.1. Remove
that to avoid this.

swrast_dri.so fails to load as well, because apparently it was built without
--enable-glx-tls.


The result is probably GLX indirect rendering, and the crash is probably
related to that. We'll need to see a backtrace from gdb, but note that GLX
indirect rendering is not expected to be stable with glamor at this point
unless glamor is from xserver Git. It may just be coincidence that it happens
to work without Ilia's commit but crashes with it.
