--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
What you need to do is build a native compiler first and install it somewhere
(does not matter where; maybe say using --prefix=${HOME}/native-build).
And then set PATH env to include ${HOME}/native-build/bin and then build the
cross compiler using that new compiler.
