commit 91cfa92a0d58379f882eb01ce3e78b5f3fc6cfa5
from: Omar Polo <op@omarpolo.com>

fix -hopefully once and for all- the readline stuff

It's incredible how hard is to find an optional dependency that's needed
only for some targets.  I don't want to use a subdir because kamiftp
needs the whole compat stuff as everything else, damn!
