   I don't think so. The linker sections work just as before.

But you changed elf_finish_pointer_linker_section, in a way which
appeared to be significant.

   But adding a symbol does not affect any section's size, except the
   symbol table section, but anyway its size a computed afterwards.

The size of the dynamic symbol table section, on the other hand, is
computed in size_dynamic_sections.
