The reason is that tarantoolctl needed for testing vshard module.
-DENABLE_DIST=ON option is used to enable tarantoolctl during «make install».

It doesn’t work, because some tests use git history:
TEST: reload_evolution/storage.test.lua
...
  vshard_copy_path = util.git_checkout('vshard_git_tree_copy',                    \
                                       last_compatible_commit)

As we discussed in chat — latest version of vshard will be used.
