python: Add patch for 64bit platform
This patch was added for 64bit host machines. In the compile process python is checking if platform is a 64bit platform using sys.maxint which is the host's value. The patch fixes this issue so that python would check if TARGET machine is 64bit not the HOST machine. In this way will have "dl" and "imageop" modules built if HOST machine is 64bit but the target machine is 32bit.
