amd64 build failure

[Paul Goyette <paul%whooppee.com@localhost>]

I ama repeatably getting the following error when trying to build HEAD

nbmake[9]: don't know how to make sandbox-rlimit.c. Stop

nbmake[9]: stopped making "dependall" in /build/netbsd-local/src_ro/crypto/external/bsd/openssh/libexec/sshd-session

This is with the following build.sh command:

===> build.sh command:    ./build.sh 		\
	-T /build/netbsd-local/tools/x86_64/amd64 \
	-D /build/netbsd-local/dest/amd64	\
	-O /build/netbsd-local/obj/amd64	\
	-R /build/netbsd-local/release		\
	-V RELEASEMACHINEDIR=amd64		\
	-V MKDEBUG=yes				\
	-V MKDEBUGKERNEL=yes			\
	-V MKDEBUGLIB=yes			\
	-V KERNEL_DIR=no			\
	-U -x -N0 -m amd64 -j50 release
