Yep. Link the binary (i.e. "date") statically or run it inside jail/chroot.
Otherwise, /libexec/ld-elf.so.1 references the host system, which on amd64
wouldn't recognize aarch64 shared libraries.

That page is a bit out of date. Nowadays building for aarch64 is as simple as

  $ pkg install poudriere qemu-user-static
  $ service qemu_user_static onestart
  $ poudriere jail -cj 111aarch64 -a arm64.aarch64 -v 11.1-RELEASE
  $ poudriere bulk -j 111aarch64 category/port

To speed up port builds you may want to consider using native
cross-toolchain by creating a jail with -x flag.
