-     doing this relocation the code in write.c is going to call
-     bfd_install_relocation, which is also going to use the symbol
-     value.  That means that if the reloc is fully resolved we want to
-     use *valuep since bfd_install_relocation is not being used.
-     However, if the reloc is not fully resolved we do not want to use
-     *valuep, and must use fx_offset instead.  However, if the reloc
-     is PC relative, we do want to use *valuep since it includes the
