[rc5] CPU autodetect

If the NFS host is a unix machine, just make symbolic links to the main
exec and name the links with the cpu type.  "ln -s rc5v2.exe
rc5v2-p5.exe" when done this way, the config file generated will be the
same basename as the executable, ie rc5v2-p5.ini when rc5v2-p5.exe
-config is run.  Then just make one link for each cpu type you need to
support.  Simple workaround.
