The attached patch (undo my other patch first) implements something like
this without actually loading libGL dynamically. It uses
dlopen(NULL, ...) to get a handle for the main program (including
libGL). I hope this is portable. Does this work for you?

Note that the patch also changes the Imakefile. In xc/programs/xdriinfo
run this to update the Makefile:

        make Makefile
        make depend

Then recompile xdriinfo as usual.
