	* elf32-arm.c (elf32_arm_final_link_relocate): Always fill in the
	GOT entry here, rather than leaving it to finish_dynamic_symbol.
	Only create a dynamic relocation for local references if
	info->shared.
	(allocate_dynrelocs_for_symbol): Update dynamic relocation
	allocation accordingly.
	(elf32_arm_finish_dynamic_symbol): Don't initialise the GOT entry here.

ld/testsuite/
	* ld-arm/exec-got-1a.s, ld-arm/exec-got-1b.s, ld-arm/exec-got-1.d,
	ld-arm/unresolved-1.s, ld-arm/unresolved-1.d,
	ld-arm/unresolved-1-dyn.d: New tests.
	* ld-arm/arm-elf.exp: Run them.
