The macro MICROBLAZE_BREAKPOINT is set to an instruction opcode that does not meet the criteria for software breakpoint instruction as set forth in the AMD MicroBlaze ISA. This patch  addresses the problem.

This simple patch concludes a series of patches that add AMD MicroBlaze gdbserver target support for GNU/Linux.

Updated NEWS to include MicroBlaze gdbserver target.

Build/Test - tested by building microblazeel-linux-gdb and verifying that software breakpoint works

using gdbserver as target.
