[ODE] Old makefile build system

Ah, you're right, I looked thru the gcc manual, the variable you want to 
set is LIBRARY_PATH sans the LD_ prefix, my mistake:

|LIBRARY_PATH|
    The value of |LIBRARY_PATH| is a colon-separated list of
    directories, much like |PATH|. When configured as a native compiler,
    GCC tries the directories thus specified when searching for special
    linker files, if it can't find them using |GCC_EXEC_PREFIX|. Linking
    using GCC also uses these directories when searching for ordinary
    libraries for the |-l| option (but directories specified with |-L|
    come first). 

Also, I ran configure on a Fedora Core 4 machine here, and it seems to 
look for and find the path for both headers and libs for X, something 
must have changed about the way configure looks for it since Redhat 9.

I made the changes so GLU is tested having GL as part of LDFLAGS, that 
should work now, I have no idea what exactly is going on
with the library path issue, but setting LIBRARY_PATH  would likelly help.

Cheers!
