Title: Makefile: change the way VERSION is generated

Issues:

- If we're building from a release tarball, VERSION is not set
- If we're building from another git repo (fork / packaging repo), and
using our own tags, VERSION is set to something that doesn't not
reflect the real version.

This patch fixes both issues, while keeping the default behavior while
building from the main git repo.
