It's not actually used in that file, but goes with hash_name() and
full_name_hash(), so it's simplest to keep it there.
Also simplify the prototype of full_name_hash to be take
a "char *" rather than "unsigned char *". That's consistent
with hash_name().

Microblaze is an FPGA soft core that can be configured various ways.
