Attempting to clear the PARALLEL_ARGS_FILE variable when it was not set would cause the above error message. Clear it only when we know we are using it. This bug was only triggered when using the 'deb' target, as it invokes the copy-firmware.sh script without any '-j' argument, while the other install targets end up passing '-j1' when not using parallel compression. * copy-firmware.sh [NUM_JOBS > 1]: Only clear the content of PARALLEL_ARGS_FILE when this condition is met.
