chesstool for 4.0

How about that.  I tried to start up /usr/games/chesstool, and the "chess"
binary is missing here too, on a 3/60 running 4.0x.  I had noticed earlier
when perusing the error message strings that the chess system seemed to
run a pipe or something between two processes -- guess back the old days
it wouldn't all fit in core.

[[ Not really.  "chess" predates "chesstool" by many years.  One of the
fulcrums of the Unix philosophy is connecting tools together with pipes.
Why reimplement "chess" when you don't have to?  "gammontool" works the
same way.  So does "bc".  --wnl ]]

And thanks to the one poster for discovering the "strings" utility
(though we'd already written our own, sort of).
