There isn't --- configure is just sloppy in that it supplies the same
library list for all programs we build. (This might be a fair amount
of work to change; never looked at it.)
However, I don't see what that has to do with the licensing argument.
We stand or fall on psql's use of libreadline, and having useless
dependencies from other executables doesn't alter anything that I can
see.
