Crafty is an open source chess engine. The former version is
very old, not to mention broken when compiling enormous opening books
(see pr ports/116163) This updates to the newest version, and solves
the problem as well. Sorry about the prior pr with this topic - the
makefile had a couple typos.

This seems to be an abandoned port. If the maintainer is no
longer interested, I will volunteer to take over this port.
