gitlab-ci: enable test build on alpine linux

Alpine is especially interesting because it uses musl as libc.

The build does not yet succeed. There are several issues that
need to be fixed.

However, it will be simpler to fix things, if we have tests
in place -- even if at the moment they are known to be broken.
