Pull up following revision(s) (requested by pgoyette in ticket #761):

        sys/compat/netbsd32/syscalls.master: revision 1.132
        sys/compat/netbsd32/netbsd32_compat_43.c: revision 1.60

Properly mark netbsd32_compat_43 syscalls that are directly implemented
by calling their compat_43 equivalents.  With these changes, and with
built-in versions of COMPAT_NETBSD32, COMPAT_NOMID, and COMPAT_09, I can
now run a netbsd-0.9 statically linked i386 (32-bit) version of /bin/ls
on a 9.99.x amd64 host!

Addresses PR kern/55047 but more changes coming to handle non-built-in
modules.
