By default, "git am" uses the time of commit creation as the committer
date and is therefore "unique" to each build.

Use the --committer-date-is-author-date option for git to use the author
date as the committer date to get deterministic meta-data and therefore
commit hashes (which may end-up in sources or build in the form of e.g.
localversion file).
