The same way you'd choose between any two programs in different locations.

You could adjust your $PATH or write a script which calls the one you want.

I have a handful of versions installed in ~/gcc/ and invoke them via a
script like

#!/bin/bash
: ${ver:=4.7}
: ${libdir:=lib64}
$HOME/gcc/$ver/bin/g++ -Wl,-rpath,$HOME/gcc/$ver/$libdir -Wall -g "$@"
