From eb858c60d7850fc2ed2f69397f0560e707de324d Mon Sep 17 00:00:00 2001

Subject: [PATCH] GIT-VERSION-GEN: detect dirty tree and mark the version
 accordingly.

If we are building from a working tree with local modifications,
mark the version accordingly.

Deliberately uses '-' to prevent RPM from being built from such
a tree.
