Nit: Use imperative mood in a commit header. See
https://tarantool.io/en/doc/1.10/dev_guide/developer_guidelines/#how-to-write-a-commit-message

The Travis-CI changes looks okay for me.

I have comments re CMake changes, see below. I added proposed changes on
top of your commit. Please, if you are agree, test them and squash.

Then, please, send the next version of the patch to one of maintainers.

WBR, Alexander Turenko.

According to [1] `make MACOSX_DEPLOYMENT_TARGET=10.6` is enough, so we
can get rid of this `if` and just set it always to 10.6.

We can add MACOSX_DEPLOYMENT_TARGET="${luajit_osx_deployment_target}" into
set(luajit_buildoptions ...) below instead.

No need to set provide env if we'll add it MACOSX_DEPLOYMENT_TARGET to
${luajit_buildoptions}. It looks simpler.

The same.
