/* Relocate an Blackfin ELF section.
 
 
 
   The RELOCATE_SECTION function is called by the new ELF backend linker

   The relocs are always passed as Rela structures; if the section
 
   actually uses Rel structures, the r_addend field will always be
 
   zero.
 
 
 
   This function is responsible for adjusting the section contents as
 
   necessary, and (if using Rela relocs and generating a relocatable
 
   output file) adjusting the reloc addend as necessary.
 
 
 
   This function does not have to worry about setting the reloc
 
   address or the reloc symbol index.
 
 
 
   LOCAL_SYMS is a pointer to the swapped in local symbols.
 
 
 
   LOCAL_SECTIONS is an array giving the section in the input file
 
   corresponding to the st_shndx field of each local symbol.
 
 
 
   The global hash table entry for the global symbols can be found
 
   via elf_sym_hashes (input_bfd).
 
 
 
   When generating relocatable output, this function must handle
 
   STB_LOCAL/STT_SECTION symbols specially.  The output symbol is
 
   going to be the section symbol corresponding to the output
 
   section, which means that the addend must be adjusted
