Yep, this is just silly... :-(

If we want a slightly less-silly-looking version, we could use something
like:

    glibc-2.26-43-gfdf58eb

whichh means the sha1 'fdf58eb' that is '43' commits after the 'glibc-2.26'
tag. But we have to be careful about shortening the sha1, to avoid
collisions. I would say that we stay with the full sha1.

It is pretty easy to generate such a version string:

    git describe --match 'glibc-*' --abbrev=12 origin/release/2.26/master

I would say that we should switch to using the 2.26/master branch from
upstream, because we don;t have the bandwidth to assess whether we
need/want to backport individual patches.

If upstream commits on the maintenance branch, it means that it is a
fix. And we want fixes, whatever they fix: functionality or security.

So I'd say we should switch to git. The repo is even accessible through
https (although it is not documented): https://sourceware.org/git/glibc.git
