glibc Versions
List of oldest supported version of top 10 Linux Distros and their glibc version according to distrowatch.com.
Summary
Out of all versions with published EOLs, 2.12 is the oldest glibc still active, found in CentOS 6.8.
Not all versions include EOLs, but going back to 2011 releases everything else is at least 2.12.
If we need to support 2.14+ then we have to cut off support for Debian 7 and CentOS 6.8 despite those versions still being supported.
