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. -- Serguei Mokhov
