If the user currently tries to use the -kernel parameter, simply nothing happens, and the user might get confused that there is nothing loaded to memory, but also no error message has been issued. Since there is no real generic way to load a kernel on all CPU types (but on some targets, the generic loader can be used instead), issue an appropriate error message here now to avoid the possible confusion.
