[Patch 1/5] ld for ia64 VMS: Minor tweaks in elflink.c

[Tristan Gingold <gingold at adacore dot com>]

Hi,

on VMS we have the dynamic sections, but no .dynsym.  So we need to adjust a few tests in elflink.c

	* elflink.c (elf_link_output_extsym): Add a guard.
	(bfd_elf_final_link): Remove assertion.
	(bfd_elf_final_link): Add a guard.
