Stop the BFD library from automatically converting OS and PROC specific symbol section indicies to SHN_ABS, and provide a hook for backends to decide how such indicies should be processed.
* elf-bfd.h (struct elf_backend_data): Add symbol_section_index
callback.
* elfxx-target.h (elf_backend_symbol_section_index): Provide
default definition.
(elfNN_bed): Initialise the symbol_section_index field.
* elf.c (swap_out_syms): Call symbol_section_index, if defined, on
OS and PROC specific section indicies. Warn if converting other
reserved incidies to SHN_ABS.
