2018-07-17  Kyrylo Tkachov  <kyrylo.tkachov@arm.com>

	Backport from mainline
	PR target/84168
	2017-09-28  Joseph Myers  <joseph@codesourcery.com>

	* config/aarch64/aarch64.c (aarch64_elf_asm_constructor)
	(aarch64_elf_asm_destructor): Pass SECTION_NOTYPE to get_section
	when creating .init_array and .fini_array sections with priority
	specified.
