If building a cross-compiler for upstream submissions or regression runs I always bootstrap a native compiler of the same checkout first and then use it for the build. I think it's good practice, and it's needed for the Ada frontend anyway. That's one way to avoid introducing warnings by chance, and it takes less than an hour to bootstrap native GCC on decent contemporary hardware (and then you don't have to be pedantic, and neither I am, and you can keep reusing an older native build for some time).
