libreadline rl_message() and building the same object file 6 times?

I *think* its safe to change this invocation of rl_message to omit the
third argument, but I'm not 100%.

Second, why on earth does a buildworld emit this warning 6 times?  Its
as though bmake things it needs to compile it repeatedly, and its not
the only such time I've seen this across the tree.  This probably means
I don't know what I'm doing, but I'd like to know.
