Add MicroBlaze support for libdebugger. This uses only software break type instructions to provide self-hosted GDB debugging support for applications since internal control of debug hardware is not possible. Also of note, this implementation for MicroBlaze would typically use the brki instruction for software break, but instead uses an illegal opcode to manage software breaks as exceptions. This is due to poor interaction with the debug hardware where the debug hardware will intercept software breaks instead of allowing the software break vector to execute.
