Compatibility support fgetln() on Linux. This uses the BSD-licensed
implementation from NetBSD tnftpd, Christos Zoulas (copyright message
retained in the compat_fgetln.c file). Patch verified by schwarze@. He
notes that you'll need -pthread for -static binaries (due to libdb), so
I've noted that -static should really only be used for BSD UNIX.
While here, add some forgotten goop to the Makefile, building and
cleaning extra manpages.
