* Make CrossCompile a proper enum type rather than a string literal, * Introduce methods to get the correct host/build chroots depending on the cross compile type and target architecture. * Remove autodetect.chroot() since it doesn't do what we expect, adjust all users to use cross.build_chroot() instead. * Refactor package building to correctly use cross.host_chroot() and cross.build_chroot().
