Comment:

 (In [9dc28b2ce920274432da72f78419562d9365bc2b]) Fix libedit detection on
 *BSD OS's

 The following patch allows the autoconf script to detect the presence of
 libedit when there isn't a pkg-config file present and thus allowing
 Varnish to detect libedit on OpenBSD/FreeBSD/NetBSD/DragonFly.

 Fixes: #1003
