    src.opts.mk: Comment about CTF & DTRACE relationship
    
    WITH_CTF enables building userland components with CTF, and not the ctf*
    tools as one might expect.  The tools are actually included with the
    DTRACE knob.  Add a comment where the dependency is handled, as this has
    caused confusion.
