If you build on random developer's machines rather than a unified build environment you've already failed at so many things that the glibc problem is certainly not your biggest concern.
Regardless it's still a PITA to maintain an ancient distro as a build environment and the alternatives are hacky. It might be the best of the linux libraries but it's still not good.
