[ODE] Old makefile build system

[Peter Kyme]

I was using the old makefile system, but I've switched to the autotools 
setup this week since the old system seemed to be falling out of 
maintenance.

I have however experienced a couple of problems, which I suspect are 
related to my system (I'm running Redhat 9, automake-1.9.6), but I'll 
detail them here anyway.

For reasons which I didn't fully get to the bottom of, the libGLU check 
fails. I hacked around this by adding the following line to configure.in

GL_LIBS="$GL_LIBS -L/usr/X11R6/lib/ -lGLU -lXmu -lXi"

I also found that the configure options for --enable-release and 
--enable-double-precision weren't working correctly. Finally, the 
#define dNODEBUG wasn't being set even when release mode was enabled.

Following is a diff that fixes these problems on my system.
