Subject: bfd/ 	* 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.
