Unfortunately I don't have an ia64 system available to debug this.
Can you help out?  Possibly there is a miscompilation of ld2?  How
does ld2 differ from ld1?

ia64 was one of the targets that didn't have any problem with its
treatment of warning symbols, except for elflink.c
_bfd_elf_export_symbol looking at h->dynamic before following a
warning symbol link, and that one is unlikely to trigger in the
bootstrap tests..  The files that did have problems were

	* elf32-arm.c (elf32_arm_to_thumb_export_stub): 
	* elf32-m68k.c (elf_m68k_init_symndx2h_1): 
	* elf32-spu.c (allocate_spuear_stubs, build_spuear_stubs): 
	* elf32-vax.c (elf_vax_instantiate_got_entries): 
	* elf64-alpha.c (elf64_alpha_merge_ind_symbols): 
	(elf64_alpha_size_plt_section_1): 
	* elf64-hppa.c (elf64_hppa_mark_exported_functions): 
	(allocate_global_data_dlt, allocate_global_data_plt): 
	(allocate_global_data_stub, allocate_global_data_opd): 
	(allocate_dynrel_entries): 
	(elf64_hppa_mark_milli_and_exported_functions): 
	(elf64_hppa_finish_dynamic_symbol, elf64_hppa_finalize_opd):

	* elflink.c (_bfd_elf_export_symbol): 
	* elfxx-mips.c (mips_elf_count_global_tls_entries): 
	(mips_elf_count_global_tls_relocs, allocate_dynrelocs):
