fc-iram: added '+' to getopt magic string like in fc-xram Both fc-iram and fc-xram now support secondary program invokation. If the user needs to pass some options to the secondary program, we don't want fc-iram or fc-xram to claim these options as its own, thus we need to stop getopt() from reordering arguments. This fix was already implemented in fc-xram a long time ago, but the issue was overlooked when secondary program invokation ability was added to fc-iram.
