/* Relocate a META ELF section.

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 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
accordingly.  */
