Right, now I see what you mean. The build process does not rely on static metadata in the source tree to determine the version, and is instead poking the git checkout to determine what the version is? That's not established practice. You should write the version into a file in the source tree, then create a commit, then tag that commit with the version.
Alternatively, you could pass in ${PV} to the build process instead as a command line parameter.
