Fixed, thanks!

Use 'ninja' instead:

-B . -S .

or even do everything (confgure and build) using CMake:

-B . -S .

Hmm, it works fine for me (see output above).

But yes, luacheck has a problems with running OOS. See description of 
the problem in [1].

The problem was workarounded in Tarantool source repository, see commit:

commit af448464d15f60b87f1c9ef41a7816911c889459

     tools: fix luacheck invocation in different cases

     Now `make luacheck` gracefully handles different cases[^1]: in-source
     and out-of-source build (within the source tree or outside), current
     working directory as a real path or with symlink components.

     As result of looking into those problems I filed the issue [1] against
     luacheck. It seems, there are problems around absolute paths with
     symlinks components.

     [^1]: We have the similar problems with LuaJIT's luacheck rule. They
           will be fixed in a separate patch.
