This is only if you run configure directly. If you build Wine using
the ports system everything is set up for you.

Well, the flag isn't FreeBSD specific. It works on all ELF targets
(including Linux which then wouldn't need prelink).

It's to make sure prelink isn't run when image base has already
been handled.
