I don't know of one, other than a mass rebuild (which is something
that I have never done myself).

A cheap proxy may be to look under /usr/bin /usr/lib etc. for
binaries with DTNEEDED readline, and then compare all of readline's
extern symbols with the binary binaries' set of extern symbols,
check for overlap in symbols that are not prefixed "rl_".
