See PR pkg/52452.  The problem is that /usr/pkg/lib/libGL.so.1.2.0 (part
of "graphics/MesaLib") runs afoul of PAX MPROTECT since it was enabled
by default on i386.  It causes the run-time linker ('ld.so_elf') to
attempt a RWX mapping of the library, which is forbidden (must not have
both W and X).

The problem has been fixed in pkgsrc-HEAD with MesaLib-11.2.2nb6.
If you update "graphics/MesaLib" to HEAD, rebuild and re-install
(or replace) it, Xorg will start.

(Or at least get further, depending on your video card and its
DRM driver status.)
