To link against a non-shared readline library, you'll need to also
specify whichever library provides termcap/terminfo functionality for
your system, typically -ltermcap or -ltinfo. (This is true for all apps
that try to link libreadline.a, not just lua; it doesn't apply when
linking a shared libreadline because the dependency is already set up
when the library was linked in that case.)
