It's already so marked in dl-sysdep.c. Failure to so mark
in the header file leads the compiler to believe that the
variable should be addressable via the .sdata section.

If a binary gets invoked by passing it as argument to ld.so the stack
still holds the auxiliary vector of ld.so when entering the _start
routine of the executable. So the invocation via ld.so is not fully
transparent to the executable. This causes problems if the executable
wants to scan the auxv itself.
Some symbols have to be identified process-wide by their name. This is
particularly important for some C++ features (e.g., class local static data
and static variables in inline functions). This cannot completely be
implemented with ELF functionality so far. The STB_GNU_UNIQUE binding
helps by ensuring the dynamic linker will always use the same definition for
all symbols with the same name and this binding.

* sysdeps/generic/libc-tls.c (__libc_setup_tls): Set l_tls_offset to
the right variable.
* elf/dl-load.c (_dl_map_object_from_fd): Use p_vaddr, not p_offset,
to compute memory location for l_tls_initimage.
* elf/rtld.c (_dl_start): Likewise.
* sysdeps/generic/libc-tls.c (__libc_setup_tls): Likewise.
* libio/oldiopopen.c: Move #include's before #if SHLIB_COMPAT,
because the .d file is generated in the non-shared case and
so fails to catch them otherwise.
* sysdeps/generic/dl-tls.c (_dl_allocate_tls_storage): New function,
split out of _dl_allocate_tls.
(_dl_allocate_tls_init): Likewise.
(_dl_allocate_tls): Call those.
* sysdeps/generic/ldsodefs.h: Declare them with attribute_hidden.
* elf/rtld.c (dl_main): Call them separately instead of calling
_dl_allocate_tls. Delay _dl_allocate_tls_init until after relocation
is finished, so that the initializer data has been relocated before we
copy it into the main thread's TLS block.
* sysdeps/generic/dl-tls.c (_dl_allocate_tls): Fix off-by-one error in
loop conditions, prevented the last used module from being initialized.

* elf/do-lookup.h [!VERSIONED]: Add new parameter flags. Use it to
check whether the caller prefers getting the most recent version of
a symbol of the earliest version.
* elf/dl-lookup.c: Adjust all callers of do_lookup. Change
_dl_do_lookup to also take the new parameter and pass it on.
Change 'explicit' parameter of _dl_lookup_symbol and
_dl_lookup_versioned_symbol to flags. Adjust tests.
* sysdeps/generic/ldsodefs.h: Adjust prototypes.
* elf/dl-libc.c: Adjust all callers of _dl_lookup_symbol and
_dl_lookup_versioned_symbol.
* elf/dl-reloc.c: Likewise.
* elf/dl-runtime.c: Likewise.
* elf/dl-sym.c: Likewise.
* sysdeps/mips/dl-machine.h: Likewise.
2002-04-08 Ulrich Drepper <drepper@redhat.com>
* cppflags-iterator.mk (cpp-srcs-left): Define NOT_IN_libc instead
of NOT_IN_LIBC.
* include/libintl.h: Test for NOT_IN_libc not NOT_IN_LIBC.
* include/stdlib.h: Likewise.
2002-04-08 Jakub Jelinek <jakub@redhat.com>
* elf/Makefile (CFLAGS-.os): Define NOT_IN_libc and IS_IN_rtld
instead of _RTLD_LOCAL.
* elf/dl-dst.h: Use IS_IN_rtld instead of _RTLD_LOCAL.
* include/unistd.h: Likewise.
* sysdeps/generic/ldsodefs.h: Likewise.
* stdio-common/_itoa.h (_itoa_word): Only use internal digit arrays
if in libc or ld.so.
* include/stdlib.h: For libc itself replace MB_CUR_MAX definition
with one accessing the locale data structures directly.
* stdio-common/printf-prs.c: Include localeinfo.h for new
MB_CUR_MAX definition.
