What about using pkg-config to probe for opengl and
get the correct linker options? Then static linking would
also be fixed (it needs more than -lX11):

$ pkg-config --libs gl
-lGL 
$ pkg-config --libs --static gl
-lGL -lm -lXext -lX11 -lpthread -lxcb -lXau -lXdmcp 

(tested on a Debian GNU Linux host)
