+[PATCH] fix move_to_unaligned32() for !x86
+
+get_unaligned() got changed into move_{from,to}_unaligned() in r24334, but
+the temporary variabled used to make sure we can take the address of the
+source argument for memcpy() got removed. Later on in r26068 dnsd.c got
+changed to call move_to_unaligned with htons/htonl as source breaking
+the build for !x86.
+
+Fix it by reintroducing the temporary variable.
