they have not licensed it to other manufacturers.  Xilinx is the only
possible specification which meets the definition in Autobook.

Perhaps this would be better as "microblaze*-*-linux" like other targets.

Thanks.  I haven't been following gdb-patches until now.  :-\

gcc/config.gcc has "microblaze*-*-*" and "microblaze*-linux*".
This should be updated to be compatible.
