+   if only to serve as a learning tool.
+
+   The RELOCATE_SECTION function is called by the new ELF backend linker
+   to handle the relocations for a section.
+
+   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 relocateable
+   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 relocateable 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
