The problem is, configure is not picking up the location of -lGL. If
you look in your config.log and search for GL, then you should see
what kind of error is there. The X stuff is looked up first then the
GL stuff and then Motif. I'm betting that the standard X lookups from
AutoConf don't store the LDFLAGS for further processed commands as we
do with Motif. If that's the case, we can just move the Motif checks
before the OpenGL checks.
The reason it works when you set the LDFLAGS is that then configure
can find the link library libGL.a or libGL.so.

This error with OpenGL not X. It appears that you do not have OpenGL

tests. Where is your OpenGL libs located?
Eh, but why do I not have these problems when I set
"setenv LDFLAGS -L/usr/X11R6/lib" before running the configure
and make?
I believe that the "/usr/X11R6/lib" is simply forgotten somewhere
in the configure/make process. But where exactly?
Here is what you ask for:
$ ./configure --prefix=/opt \
--x-includes=/usr/local/include:/usr/X11R6/include \
--x-libraries=/usr/local/lib:/usr/X11R6/lib > configure.output
$ grep -i gl configure.output

The last three Makefile's are such that only opengl has work
to do; nothing to be done in xgl/ and gl/. Should make sense, no?
Moreover:
$ cd src/exec/hwrender/opengl
$ make
has no errors at all!! Does that give a hint?
