Looks like you may have some left over cruft from a previous driver install that is blocking the build process.

Check if our driver is loaded...
lsmod | grep aja
If the output is blank then our driver is not loaded and you can proceed. If you get an output that looks like
ajantv2 1863680 3, then the driver is loaded and you can stop here.

If you still want to rebuild the driver after it has been loaded, then you will need to uninstall the driver.

Assuming the driver is not loaded, lets cd to the correct directory, clean the build area, and attempt to build the driver again...
cd libajantv2/driver/linux
make clean

If the make clean command fails with similar error listed above, you may need to run the command as root to get the right permissions.
sudo !!

Assuming this was successful, try to make the driver again...
make

To install the driver using dkms, run the following command...
make dkms-install

Let me know if this works for you.
