Subject: [PATCH] Reapply "build: Don't check parent directories for git tag"

This reverts commit 7e0c25eccd8d9bc5b77953dbc9a39a26e383c550.

The `--git-dir` argument is relative to the `-C` argument, making this
patch OK after all.

I added a comment to go along with this since I found it confusing.

Apologies for the revert.
