[PATCH] GIT-VERSION-GEN: Use standard versioning suffix

From: Jonas Rebmann <jre@pengutronix.de>
Date: Sep 5, 2025, 12:14 UTC
Message-ID: <20250905-semver-v1-1-3f6dd32f71a3@pengutronix.de>

In snapshot builds of git, git-version uses a modified variant of the git-describe output, e.g. 2.51.0.178.g2462961280 instead of 2.51.0-178-g2462961280 for seemingly historical reasons.

This is not semver compliant which makes the output harder to parse in tooling such as b4, which currently errors out when using a snapshot build of git.

For snapshot builds, use as version string the unmodified git-describe output with only the leading v stripped from the tag.

Fixes: 5c7d3c9507f7 ("Allow building of RPM from interim snapshot.")
