Unfortunately that doesn't suffice.

When compiling libobjc/linking.m the compiler outputs ".uaxword" in
order to output a double int.  Changing UNALIGNED_DOUBLE_INT_ASM_OP
to return NULL when ! TARGET_ARCH64 causes the bootstrap to fail
because the dw2_asm_output_* routines assume that unaligned_integer_asm_op
always returns a string.

assemble_integer is capable of outputting unaligned integers and
knows how to output a double int even when UNALIGNED_DOUBLE_INT_ASM_OP
is NULL.  The patch replaces unaligned_integer_asm_op with assemble_integer.
