re PR target/91306 ([MSP430] libgcc/crtstuff.c: Alignment of frame_dummy .init_array...

2019-08-23  Jozef Lawrynowicz  <jozef.l@mittosystems.com>

	PR target/91306
	* crtstuff.c (__CTOR_LIST__): Align to the "__alignof__" the array
	element type, instead of "sizeof" the element type.
	(__DTOR_LIST__): Likewise.
	(__TMC_LIST__): Likewise.
	(__do_global_dtors_aux_fini_array_entry): Likewise.
	(__frame_dummy_init_array_entry): Likewise.
	(__CTOR_END__): Likewise.
	(__DTOR_END__): Likweise.
	(__FRAME_END__): Likewise.
	(__TMC_END__): Likewise.
