This last thing will probably cause problems in the future: when we will add new glibc patches, they may not work with the ARC version of glibc, or when we bump to glibc 2.26.1, the ARC version of glibc will probably not be rebased at exactly the same time. So I've left it as-is for now, but I'm pretty sure we'll have to switch to per-version directories very soon.
