matthieu@ tried to address these two issues, see

  https://github.com/openbsd/ports/commits/master/devel/readline

Since it unbreaks detection of devel/readline it results in ports
picking it up, resulting in hidden deps or breakage during bulk
builds.  Neutering these hidden deps in existing ports or moving the
.pc to ereadline.pc could be a solution, as discussed by matthieu@ and
ajacoutot@.  No idea what's the best way forward, nor whether we
should actually do anything at this point in the release cycle.
