Currently, we do a full git clone of the repository, which takes quite some time, especially on slow networks. This was done like that because the initial patch was using the official repository as the source of the download, and that repository did not offer remotely-generated tarballs. But now we've switched to using a mirror on github, which does provide such a tarball, which provides faster downloads. Use that. However, the tarball from github differs from the one we were generating locally, because the paths inside are different. WE used to create a archive with paths starting with glibc-glibc-2.26-73-g4b692dfb95[...], while github does away with the git-describe prefix, and generates paths that start with just glibc-4b692dffb95[...]. The content are exactly identicall (checked with a diff), though. Update the hash accordingly. Signed-off-by: "Yann E.
