	* elf32-arm.c (elf32_arm_stub_type): Add arm_stub_a8_veneer_lwm.
	(arm_build_one_stub): Build a8 veneers as a separate pass.
	(cortex_a8_erratum_scan): Add prev_num_a8_fixes and stub_changed_p
	parameters.  Use them to check if we create a different a8 fixup
	than the previous pass.
	(elf32_arm_size_stubs): Move scope of stub_changed and
	prev_num_a8_fixes into main loop.
	(elf32_arm_build_stubs): Build a8 veneers in a second pass.
