Lua 5.5 introduces support to open readline with dlopen, so you no longer need readline to execute your srcipts, but can still get a nice interactive Lua when readline is installed. Enable this feature so readline only is a soft dependency. Upstream uses libreadline.so, which is unacceptable for us. Instead, extract the soname from the library and use that.
