Find out which architecture we are running onAuthor(s): Manuel Carro, Robert Manchek.
The architecure and operating system the engine is compiled for determines whether we can use or not certain libraries. This script, taken from a PVM distribution, uses a heuristic (which may need to be tuned from time to time) to find out the platform. It returns a string which is used throughout the engine (in #ifdefs) to enable/disable certain characteristics.
