    Sure, and unrolling loops can cause cache misses and be slower than that
    jmp back in a loop. The point is this is a string, the people who think
    they're able to hand diddle the options can change it. And more to the
    point anyone who can't find a string in a makefile shouldn't be second
    guessing the compiler anyway.
