	* Makeconfig: Define relro-LDFLAGS if have-z-relro==yes.  Add it to
	LDFLAGS.so and LDFLAGS-rtld.
	(+link): Add relro-LDFLAGS.
	* Makeconfig (shlib.lds): Place __libc_subfreeres, __libc_atexit, and
	__libc_thread_subfreeres sections after .jcr section.
	* config.make.in: Add have-z-relro.
	* configure.in: Add check for -z relro option.
	* include/link.h (struct link_map): Add relro_addr and relro_size
	members.
	* elf/dl-load.c (_dl_map_object_from_fd): Recognize PT_GNU_RELRO.
	* elf/dl-reloc.c (_dl_relocate_object): At the end, make relro
	part of loaded segments read-only.
	* elf/elf.h: Define PT_GNU_RELRO.
	* elf/rtld.c (_dl_start): Recognize PT_GNU_RELRO of ld.so.
	(dl_main): Recognize PT_GNU_RELRO of the application.  Call
	_dl_debug_initialize and initialize l_info[DT_DEBUG] before
	relocations.
