This reverts commitb558ff043d. This reverts commit4a11f20659. The initial import commit failed to retain local changes made to readline's configure.in (and the commit message erroneously stated that there were no local changes that needed to be reapplied). Also the import caused a couple of build errors and a scattering of testsuite regressions throughout many arches. It's probably better to start over with this import, hopefully more carefully next time.
