Using pkg-config file is indeed a correct fix. But I think we should
understand why readline doesn't install .pc file by default. This
might be a reason that it is outdated and incorrect. Yes, in past we
have fixed static linking with readline for many packages by passing
it's private libraries.

May be if we first upstream readline changes with .pc installation in
autotools files, it would be nice to use fix. Otherwise, we need to
maintain patch and .pc file updated (in case of any changes in list of
private libraries).

Thanks,
Rahul
