Subject: configure: restore readline test fallback
Patch-mainline: Never, Leap 15 build hack
References: none

Restore the fallback to "-lreadline" in case pkgconfig check for readline
library fails because readline library is available but lacking the
pkgconfig files.

Fixes: 8f0420c533ae ("build: Allow building with libedit instead readline")
