--- Comment #14 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So the problem is host_extra_objs gets included in libbackend.a but since
nothing references it inside the static library, it does not get linked into
the cc1 ...

Looks like other changes are needed to fix host_extra_objs issue here ...
