jhead fails to cross build from source, because it uses the build
architecture compiler. Looking closer, that use happens during
dh_auto_install. What happens here is that jhead gets rebuild during
dh_auto_install even though it already has been built during
dh_auto_build. Since debhelper does not pass cross tools to
dh_auto_install, this fails. The cause is the dependency on objdir.
make considers it remade all the time and therefore has to rebuild
everything else. To avoid this from happening, an order-only
prerequisite should be used. I'm attaching a patch for your convenience.
