static linking glxgears and glxinfo now fails (mult. def. _glapi_tls_Context, etc.)

Glxgears and glxinfo will no longer build in my static-linked environment.

I don't know what's changed to cause this since I last updated current
(quite some time ago, around about 8.99.32 for both src and xsrc) and
built everything, but something has, and I can't quite figure out what
to do about it.

Perhaps common "global" variables in TLS aren't being merged by the
linker?  Maybe I can/should just turn off -DGLX_USE_TLS for libGL and
libglapi?  But why do both libraries define these same variables in
objects that are pulled in?  (see below for symbols in likely modules)

Below is the patch for static-linking glxgears/Makefile (the same is
needed for glxinfo, and many similar patches are required throughout
xorg).  I had to add -lexpat since the update as well -- it was not
required for 8.99.32.

FYI, here's what's in each module that I think is causing the problems:
