90c984fc53 Properly handle indirect symbols
2012-07-03  H.J. Lu  <hongjiu.lu@intel.com>

	PR ld/3351
	* elflink.c (_bfd_elf_update_dynamic_flags): New.
	(_bfd_elf_merge_symbol): Update both real and indirect symbol
	dynamic flags.
	(_bfd_elf_add_default_symbol): Make the real symbol dynamic if
	the indirect symbol is defined in a shared library.
	(elf_link_add_object_symbols): Likewise.  If the indirect
	symbol has been forced local, don't make the real symbol
	dynamic.
	(elf_link_check_versioned_symbol): Check indirect symbol.
	(elf_link_output_extsym): Use real symbol definition when
	reporting indirect symbol error.  Check version info for
	dynamic versioned symbol.
