jlam 60207a145d Update pkgtools/libnbcompat to 20030829. Changes from previous version
include:

    * Move headers out of the global namespace and into the nbcompat
      directory.  Since there are no headers other than nbcompat.h in
      ${PREFIX}/include/libnbcompat, just install it directly in
      ${PREFIX}/include.  Using libnbcompat is now a matter of including
      nbcompat.h at the top of *.c files and linking against -lnbcompat.

    * Only build functions into libnbcompat.a if they aren't already in
      the system libraries.

    * Move several *.[ch] files that are pax- or mtree-specific out
      of libnbcompat (they should belong with those packages).

On NetBSD 1.6 systems, libnbcompat.a now contains just the bare minimum:
the sha2 routines.
