You will need different Buildroot builds yes, but you can use a single Buildroot source tree. Basically, your i.MX6 system will need one Buildroot configuration (.config file / defconfig file) and your i.MX8 system will need another Buildroot configuration (another .config file / defconfig file). You can build both configurations in parallel based on the same Buildroot source tree using "out of tree" build, see https://buildroot.org/downloads/manual/manual.html#_building_out_of_tree.
