  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 :-).
