By inspecting the tarball [1] with 'tar -tvf' I can see it contains:
instead of

I believe the hash was calculated (and the tarball [1] was generated) using tar
1.27.1 before 6e2f5d0254 "download/git: fix transform regexp for older tar
versions" (Fri Apr 20 09:36:32 2018 +0200), see my tests below.

I think we can safely update the hash value and commit it.

When the patch fixing the hash get applied, should the tarball [1] be manually
removed? Will it be automatically overwritten by an autobuilder instance?
