Delete duplicate target short-cuts to dynamic sections
We'd like to have the elf_link_hash_table srelplt field rather than
some private target field used to save short-cuts to a PLT relocation
section. This save a little space but mainly is so that the generic
ELF code can access the field. Ditto for other dynamic sections.
