Having run into this at a smaller scale for one of the projects I ended up using
devtoolset-6 (and -7 as appropriate) that ships all this stuff such as
newer GCC,
GLIBC, etc.

Me too, I ran the 4.x kernels from elrepo on EL6 and EL7 for newer
NVIDIA drivers as well...
All scripted as well, e.g.

   github.com/OpenISS/OpenISS/blob/master/src/scripts/dependencies/el7.sh

for CI servers or containers or similar.
