[PATCH] [FreeBSD 3] rl_event_hook detection

[Timur I. Bakeyev]

This patch is relevant for Samba4 source mostly. The way, how readline
compiled under FreeBSD makes it require stdio.h to get all the necessary
declarations. Without this addition rl_event_hook is not properly detected.

With regards,
Timur Bakeyev.
