I've had similar issues over in Java.
There are at least standard ways to get access to more recent gcc versions with official support (RHSCL aka Red Hat Software Collections). CentOS also supports them: https://www.softwarecollections.org/en/scls/rhscl/devtoolset-8/ This basically works by installing another toolchain to a specific location (/opt) and sourcing a file or using a provided wrapper with environment variables (PATH, LD_LIBRARY_PATH, etc.) in order to switch to the newer version. Not exactly straight-forward, but it works and should only be necessary during build, I guess.
