This problem due not occur under all configurations. For example it
does not happen with modesetting on i915 or radeon. It can be triggered
on those by setting environment variables:
This is also true for x86_64. What happens then is that glGetString()
doesn't get resolved to any implementation and glxinfo crashes.
There is only one call to u_current_set_table and we do return the same
table pointer at the time when glGetString() gets called so I don't
think the problem is in the patch. There may be code on in some of the
backends that make false assumptions about the startup value of TLS
variables. Need to compare with pkgsrc on Linux.
