lua.c loads 'readline' dynamically
(See comments in luaconf.h.) This change allows easier compilation, as Lua compiles and works even if the package 'readline' is absent from the system. Moreover, non-interactive uses don't load the library, making the stand-alone slightly faster for small loads.

62** When Posix DLL ('LUA_USE_DLOPEN') is enabled, the Lua stand-alone
63** application will try to dynamically link a 'readline' facility
64** for its REPL. In that case, LUA_READLINELIB is the name of the
65** library it will look for those facilities. If lua.c cannot open
66** the specified library, it will generate a warning and then run
67** without 'readline'. If that macro is not defined, lua.c will not
68** use 'readline'.
