Title: Makefile: Deal w/ lack of git and/or appropriate tags when determining version_build

For those who attempt to build from tarball or have forgotten/neglected to fetch tags.

This also is a much better way to find the proper tag, git already has a nice label searching mechanism:
```
git describe --match build.? --tags --abbrev=0 2>/dev/null
```
