disabling opengl in octave 3.2.2

[Jonathan Sievers]

Hey folks - I'm trying to compile octave 3.2.2 from source using icc to 
run on a cluster.  OpenGL is causing problems  - there are 
headers/libraries there which show up during configure but break during 
compilation.  Which is not a problem, I don't need graphics, but I can't 
compile.  I've look through configure several times and can't find a flag 
to disable opengl - does such a thing exist, or is there some other simple 
way to turn it off?  Everything works fine under 3.0.5.

BTW, I thought you might enjoy knowing that I now routinely run an MPIed 
octave across three to four thousand cores.  Thanks for the great work!
