patch for bfd/dwarf2.c, support for 16-bit addresses in DWARF-2

[Stephane Carrez <Stephane dot Carrez at worldnet dot fr>]

Hi!

The following patch for bfd/dwarf2.c fixes the support of dwarf2 for 16-bit
address targets. All we have to do is accept the address size of 2 and read
it accordingly.

Can you integrate this fix ?

Thanks,
	Stephane

	* dwarf2.c (parse_comp_unit): Accept addr_size == 2.
	(read_address): Recognize addr_size == 2 for 16-bits targets.
