The test, tests/tail/f-1, failed on powerpc-apple-darwin7.7.0.
(IS_TAILABLE_FILE_TYPE): Adjust definition also to include
sockets, since that's what you get when reading from a command-line-
supplied pipe on Darwin 7.7.
(IS_PIPE_LIKE_FILE_TYPE): Define.
(main): Use new IS_PIPE_LIKE_FILE_TYPE rather than simply S_ISFIFO.
This same change is also required on NetBSD/sparc-1.5.
