The compiler packages are actually based on Oracle Linux 5 so that the built JDK bits will be compatible with older Linux versions without forcing us to run the builds on older OS versions. The scripts used to generate these packages can be found in make/devkit/ in the root repo.

An alternative approach to this that we experimented with while working out how to build GraalVM images[1] that support older Linux versions was to use Docker[2]. It’s fairly straight forward and avoided the need for a completely separate VM in our case (or a from source GCC toolchain).
