* elflink.c (_bfd_elf_link_create_dynamic_sections): If the

	backend does not provide a function for creating dynamic sections
	then fail.
	(bfd_elf_final_link): Issue a warning message if a dynamic section
	has the SHT_NOTE type.
	(bfd_elf_final_link): Do not look for dynamic strings in a section
	that does not have the SHT_STRTAB type or the name .dynstr.
	* elf32-arm.c (elf32_arm_finish_dynamic_sections): Fail if the got
	section is not in the output binary.
	* elf32-hppa.c (elf32_hppa_finish_dynamic_sections): Likewise.

	* ld-elf/elf.exp: Add test for linking a shared library with a
	broken linker script that marks dynamic sections as being notes.
	* ld-elf/note-3.s: New test source file.
	* ld-elf/note-3.t: New test linker script.
	* ld-elf/note-3.l: Expected output from the linker.
	* lib/ld-lib.exp (run_ld_link_tests): Improve description.
