Hi! Thanks for the patch!

What is the difference? Is it really necessary for anything? To be
able to see CMake files in there?

This function is introduced in tarantool, but required
for luajit. On the contrary, luajit is required for tarantool.
This is cyclic dependency, which makes impossible to run such
tests inside luajit. I think luajit tests should be kept self
sufficient. Otherwise it makes no sense to keep them in luajit
repository. If you anyway can't run them in there, and need to
create some test-wrappers from tarantool's side.

Alternative is to move them completely to tarantool. But current
way is not right. It is half of one and half of other solution.
