journey in the source code, it seems the cases were ssl_ver is zero
doesn't follow the same pattern and thus turned out confusing and
misleading. For now, we skip doing any CURLINFO_TEXT logging on those

- update urls
- sync examples makefiles with main ones
- remove line ending space

This fixes using a multi-target mingw distro to build curl .dll for the
non-default target.
