[PATCH] dwarf2out.c breakage on ss2000-06-26

[Marc Espie]

Recent changes to dwarf2out.c broke OpenBSD, and probably a lot of other
platforms as well (most platforms that define DWARF2_UNWIND_INFO 0).

If UNALIGNED_INT_ASM_OP is unavailable, dwarf2out.c does not provide a
suitable definition for ASM_OUTPUT_DWARF_DATA2, even though it uses it.

The following patch restores OpenBSD to sanity.

	* dwarf2out.c (ASM_OUTPUT_DWARF_DATA2): provide in the
	case where UNALIGNED_INT_ASM_OP is unavailable.
