I'm too bad in copy-pasting... Thanks for catching! Added all necessary
flags, squashed, force-pushed to the branch. Diff is below.

Agree. BTW, it allows to check that Tarantool is not built with <strict>
enabled by default in Release. Fixed, squashed, force-pushed to the
branch. Diff is below.

Added your tags to all patches:
| Reviewed-by: Sergey Kaplun <skaplun at tarantool.org>

Furthermore, I believe it is worth to mention your origin in
LUAJIT_TEST_INIT idea, so I've added you as a co-author to the last
patch on the branch.
