reasons for this:
(1) The second and third parts will be against 0 (RSS_UNDEF) but
should nevertheless be emitted if the first part is.
(2) In normal usage, composite relocations are never assembly-time
constants. The easiest way of dealing with the pathological
exceptions is to generate a relocation against STN_UNDEF and
leave everything up to the linker. */
