Bug description:
  with rust-coreutils, cp -T fails to behave like gnucp when using it to
  copy a source directory to a target location and that location doesn't
  exist yet.

  ```
  #!/bin/bash
  set -eux

  rm -fr src dst

  mkdir src
  touch src/file.txt

  /usr/lib/cargo/bin/coreutils/cp -aT src dst

  [ -f dst/file.txt ]
  ```

  Workarounds:
  * remove -T from the cp invocation
  * mkdir dst before the cp invocation
