--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- It seems there's a libgnat_pic.a built even without --enable-host-pie, but that's not picked up by with --enable-host-pie host tools link. So the issue might be with the host gnatmake/gnatlink not understanding that -pie when doing static libada linking, should use the libgnat_pic.a library?
