All that this option does WRT linking is that it makes pcretest linked with
-lreadline. The latter usually means dynamic linking.
BTW. what the patch actually does is that it forces everything (not only
pcretest) to be linked with -lcurses in case when -lreadlink does not link
without a terminfo library, and -lcurses exists and provides "tputs".

Yes, you can implement it the portable way, but the change is not going to be
tiny and beautiful, and I'm not sure the matter worths it. But I'll attach it
anyway, just for reference.
