[ODE] ODE and Itanium processors

[Chris M.]

I modified Makefile.am to set x86_x64 and it compiled fine.  I ran a bunch 
of the test
programs and they all seemed to run fine.  Im familiar with this make 
system(autogen
its called), and
don't even know where I would add a check for Itanium processors.
