Brooks Davis 6bea876644 Add libnetbsd, a thin compatibility layer intended to allow a limited
set of NetBSD software to compile as part of the FreeBSD build with
little or no modifiction.  It is built as a static library and not
installed for general use.  Likewise, its header files are not
installed.
