Local git tags interfere with versioning

[mrvdb]

The build system uses git describe --tags | cut -c 2- to construct a version number from tags like v0.9.1 to display something like 0.9.1-102-g31fa4b0

The --tags option makes it interfere with tags local to the repository which are just pointers and not annotated with a message like the version tags.

Options to resolve the issue:

• omit --tags to only consider annotated tags, sufficient to resolve
• use a pattern check like v* or something more fancy to filter tags
• use --contains option? not sure how that would work

For now, just omitting --tags should be fine.

any comments on this? I can make a PR, but the proposed change is fairly trivial

Yeah, removing --tags is a simple enough fix. Please feel free to make a PR, and we'll get it in.
