(_dl_main): Don't set GL(_dl_loaded)->l_relro_{addr,size} here.
Call _dl_protect_relro for libraries if prelinking.

* configure.in: Define HAVE_Z_RELRO if the linker supports -z relro.
* config.h.in: Add entry for HAVE_Z_RELRO.
* include/libc-symbols.h: Define attribute_relro.
* elf/dl-load.c: Add attribute_relro to env_path_list, capstr, ncapstr,
max_capstrlen, and max_dirnamelen definitions.
* elf/rtld.c: Add attribute_relro to _dl_argc, _dl_argv, _dl_skip_args,
load_time, start_time, library_path, preloadlist, version_info,
any_debug.
Remove rtld_total_time. Make it a local variable. Pass pointer to
it to print_statistics. Change print_statistics accordingly.
* sysdeps/generic/dl-sysdep.c: Add attribute_relro to _dl_auxv. Use
attribute_relro instead of explicitly assigning variable to the
.data.rel.ro section for __libc_enable_secure and __libc_stack_end.
* sysdeps/generic/ldsodefs.h: Declare __libc_stack_end, _dl_argc,
_dl_argv, _dl_argv_internal with attribute_relro.

* sysdeps/x86_64/dl-machine.h: Include <tls.h>.
* elf/rtld.c (_dl_start_final): Initialze __libc_stack_end here.
* sysdeps/generic/dl-sysdep.c: Define __libc_stack_end with
rtld_hidden_def and move into .data.rel.ro section.
* sysdeps/generic/ldsodefs.h: Declare __libc_stack_end with
rtld_hidden_proto.
* sysdeps/generic/libc-start.c: Only initialize __libc_stack_end here
if !SHARED.
* sysdeps/unix/sysv/linux/dl-execstack.c
(_dl_make_stack_executable): Move common code in front. Use
__builtin_expect.

* sysdeps/unix/sysv/linux/dl-execstack.c: Change interface. Add
challenge for caller.
* sysdeps/generic/ldsodefs.h: Change declaration and type of hook
member in rtld_global appropriately.
* elf/dl-support.c: Likewise.
* elf/dl-load.c (_dl_map_object_from_fd): Take additional paramter.
Pass it on to the changed function.
(_dl_map_object): Pass new parameter to _dl_map_object_from_fd.
