+ The RELOCATE_SECTION function is called by the new ELF backend linker

+ 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
+ accordingly. */
