Fixed prebuilt binary compatibility with older glibc

fixes #1580

- in the issue above, a user reported the prebuilt binaries
  were not compatible with the glibc version that CentOS 7 ships with
- it looks like CentOS 7 ships with glibc 2.17
- we already had a fix for this but the transition to a new CI setup
  regressed including them during compilation
- this commit ensures the prebuilt binaries are compatible by applying
  the linking override file we already had
