Okay, that's what I thought. It just turns out that on hppa, due to the
previous implementation of function descriptors there were certain COPY
relocs that had to skipped or the initialized table for the fdesc's
would be lost. I fixed this entire mess by moving over to Lu's
generalized code and reinstating the processing of these last COPY
relocs, eveything works happily now. Thanks for the input Roland.
