	ld/testsuite/
	* ld-arm/arm-pic-veneer.d: Update expected output.
	* ld-arm/arm-call.d: Ditto.

	bfd/
	* elf32-arm.c (output_arch_syminfo): Replace plt_shndx and plt_offset
	with sec and sec_shndx.
	(elf32_arm_ouput_plt_map_sym): Use them.
	(elf32_arm_output_arch_local_syms): Output mapping symbols for
	interworking glue.
