re PR target/89361 (s390 broken without S390_USE_TARGET_ATTRIBUTE, likely since r257489)

	PR target/89361
	* config/s390/s390.c (s390_indirect_branch_attrvalue,
	s390_indirect_branch_settings): Define unconditionally.
	(s390_set_current_function): Likewise, but guard the whole body except
	the s390_indirect_branch_settings call with
	#if S390_USE_TARGET_ATTRIBUTE.
	(TARGET_SET_CURRENT_FUNCTION): Redefine unconditionally.
