* arm.cc (Target_arm::do_define_standard_symbols): New method.
 	(Target_arm::do_finalize_sections): Remove code which defines
	__exidx_start and __exidx_end.  Make symbol table parameter
	anonymous as it is not used.
	* gold.cc (queue_middle_tasks): Call target hook to define any
	target-specific symbols.
	* target.h (Target::define_standard_symbols): New method.
	(Target::do_define_standard_symbols): Same.
	* testsuite/Makefile.am (arm_exidx_test): Dump relocations also.
	* testsuite/Makefile.in: Regenerate.
	* testsuite/arm_exidx.s: Generate data relocations for __exidx_start
	and __exidx_end.
	* testsuite/arm_exidx_test.sh: Check that no unused dynamic
	relocations are generated for __exidx_start and __exidx_end.
