Do I need to compile it myself? Or maybe even the whole GCC? Going back before 2.34 if the distribution is on 2.34 or later is not really possible. You need to build a whole cross-toolchain environment. It's easier to build on an older version of the distribution? Why do you need to go back 2.31? What kind of problem are you trying to solve?
