Yes you are right.  In the end I have gone back to the patch that you
supplied and applied a variant of it. (See below).  The only real
change I made was to add an explanatory comment and to have the new
function call bfd_elf_generic_reloc() rather than incorporating the
code from that function into this function.  That way if the code in
elf.c changes you will not need to update this function.

I think that basically there is a bug in bfd_install_relocation /
bfd_perform_relocation with regard to the handling of the pcrel_offset
field.  Changing them however is not a good idea, as they are generic
functions and they are used by lots of ports.  So instead using a
special handler function is this simplest workaround.
