copy_private_symbol_data

bfd_copy_private_symbol_data is a bfd function that appeared in
commit 89665c8562da a long time ago, but seemingly wasn't used
anywhere until Jan added it to gas/symbols.c in commit 6a2b6326c21e.

The function is used to modify ELF symbol st_shndx for symbols defined
in odd sections like .symtab, so that they get the corresponding
section st_shndx in an output file.  This patch fixes some bitrot in
the function.  After commit c03551323c04 which introduced
output_elf_obj_tdata, elf_strtab_sec and elf_shstrtab_sec will
segfault if used on an input bfd.

	PR 14493
	* elf.c (_bfd_elf_copy_private_symbol_data): Don't use
	elf_strtab_sec and elf_shstrtab_sec.
