bfd/
* bfd-in.h (bfd_elf_size_dynamic_sections): Add audit and depaudit
arguments.
* elflink.c (bfd_elf_size_dynamic_sections): Generate DT_AUDIT,
DT_DEPAUDIT from audit/depaudit arguments.
(elf_finalize_dynstr): Finalize DT_AUDIT and DT_DEPAUDIT strtab entries.
(elf_link_add_object_symbols): Set dt_audit target data when finding a
DT_AUDIT.
* bfd-in2.h: Regenerate.
* bfd-elf.h: Add dt_audit to elf_obj_tdata, and elf_dt_audit macro.
ld/
* emultempl/elf32.em (gld${EMULATION_NAME}_add_options): Add --audit,
--depaudit, and -P options.
(gld${EULATION_NAME}_handle_options): Ditto.
(gld${EULATION_NAME}_list_options): Ditto.
(gld${EMULATION_NAME}_append_to_separated_string): New function for
handling rpath-like colon separated strings.
(gld${EMULATION_NAME}_before_allocation): Pass the audit and depaudit
libs to bfd. Propagate DT_AUDIT from needed libs to depaudit.
* ld.texinfo: Document new options.
ld/testsuite/
