Alexander, thanks for the review, I've made all changes as you suggested, please recheck the new version of the patch. Also I've divided the patch into 2 patch sets and left under the issue #4551 only changes for static build w/o Dockerfile.

Right, the patch divided into standalone patch set with Dockerfile
changes and patch for static build w/o it.

Right, found that after your suggestions it is not needed at all - removed.

Right, fixed as you suggested and added comments that the library will
be used if it will be found.

Building unit tests got linking errors - all of them posted at the commit
message.

It seems not good to add the died code w/o its use, seems that better
to use single commit for it.

I've made a lot checks and found that the curl tool use instead of wget
helped to resolve flaky issues, also I've added the links to the issues at
the sourceforge site to see how it happened worldwide.

Ok, I've completely rewrote the comment.

Right, it is not needed now - removed.

Created standalone patch set with 5 commits in it for each of the change.

Ok, also tried to avoid of it, and found that on Debian Stretch OS the
libunwind static library has undefined use of liblzma functions, because
there is no liblzma static library. Found that libunwind dynamic uses
existing liblzma dynamic library while, and that is why we need to install
liblzma-dev package to additionally provide liblzma static library.

Ok, as was discussed by voice decided to move static build make targets from
.gitlab.mk to .travis.mk to store it in common place with the other test/build make
targets. Moved environment from .gitlab-ci.yml file into make targets to
make this targets true building in static w/o additional setup.

Ok, I've made changes based on your suggestions.
