with_cpu is a property of the target.  Since that's the last pass to run
it should be able to set the final value of with_cpu.  So I think your
reassignment should appear at the top of each pass.  Something like

 # For the host machine, we save the xm_file variable as host_xm_file;
 # then we decode the target machine and forget everything else
 # that came from the host machine.
+arg_with_cpu="$with_cpu"
 for machine in $build $host $target; do
+       with_cpu="$arg_with_cpu"
        . ${srcdir}/config.gcc
 done
 
 extra_objs="${host_extra_objs} ${extra_objs}"
