The -v option used to print useful information when operating on a.out format libraries. After the removal of a.out support, it was accepted but did not have any effect. Remove the option and update the man-page. While here mention the set of historic options that are accepted but ignored: "-elf", "-s", and "-v". The FILES section contained outdated information and did not mention the way library directories of optional ports and packages are included in the library search path recorded in the hints file. The description of the "-B" option was incorrect (described a planned change) for big-endian platforms (powerpc64). These do still default to big-endian hints files, since the current version of the "pkg" program expects the hints file to be in native byte-order.
