You can of course use the git download method instead of the tarball.
Since you're downloading a tag, a shallow clone should work, so the
overhead compared to a tarball is limited.

To make things reproducible, it is anyway advisable to set up a
BR2_PRIMARY_SITE where the tarballs are kept. It's a bit of a pain to
maintain such a primary site, but it does solve a lot of potential issues
(e.g. the kernel.org website going down :-).
