Add support for OpenRISC - Fixed issues

This work is based on the old or32 port (that has been
removed back in 2005) authored by Chris Ziomkowski. The patch includes the
basic functions every port should implement like: context switch, exception
handling, OpenRISC ABI and machine definitions and configurations.
