[ODE] configure improvements

[Rodrigo Hernandez]

Because I used a workarround to build the shared library tricking 
autotools into thinking the .so is a program and not a lib, I did so in 
order not to rely on libtool, autotools wont let you do lib_PROGRAMS, 
and tricking lib_LIBRARIES to build a .so requires too many manual 
targets to be hacked into the code.

I have not had the time to look into how to trick the scripts into 
installing libode.so in lib.
