I saw this in the git history and did start to wonder what keeps
changing. I haven't really had much time to look into it though, I've
just gone for a fix which never assumes that printf can handle a
particular large field width.

OpenEmbedded master branch is currently using glibc 2.24 plus a bunch
of patches. I'm building for a 32-bit system if that makes a difference.
