Note that this should work if the target is passed on the command line because the command line is parsed twice to avoid
exactly this. If you need to set the target in the config, just set the target cpu and target fpu (-Cp and -Cf) as well.
As the workings of the switches is interwinded there is unfortunatly no good other solution.
