hi, Andreas:
  I checked the as-internal document, there is no something like fptr
stuff, or this is a self defined thing to handle some special
relocation type, right?
Because I don't know the powerpc assemble language, do you mind to
give me a little more detail about @fptr thing?

Thanks very much.
