Right now this is done through the gcc@5 formula.
See 9692318ca6/Formula/gcc%405.rb (L33)
This is fragile because when we will migrate to gcc@11
we have to think about migrating the installation from one gcc formula to another..
Also, not having the right glibc version results in a non-functional brew
installation on an older Linux: the glibc installation needs
to be done by brew, and not by a workaround in a specific formula
