With dynamic linking we have the current limitation that there can be only a single active data segment (since we use __memory_base as the load address and we can't do arithmetic in constant expresions). This change delays the merging of active segments until a little later in the linking process which means that the grouping of data by section, and the magic __start/__end symbols work as expected under dynamic linking.
