It doesn't work.  It outputs
	.vbyte 4	12345678
rather than
	.vbyte 4,12345678
which is required.  And no,
	.vbyte 4,	12345678
doesn't work either.

Actually, dwarf2out assumes that if UNALIGNED_INT_ASM_OP is defined,
then ASM_OUTPUT_DWARF_* are defined.  This is slightly annoying
because aix.h wants to define all the ASM_OUTPUT_DWARF_* without
defining UNALIGNED_*.
