Don't use INTVARDEF/INTUSE with __libc_enable_secure (bug 14132).
Continuing the removal of the obsolete INTDEF / INTVARDEF / INTUSE mechanism, this patch replaces its use for __libc_enable_secure with the use of rtld_hidden_data_def and rtld_hidden_proto. Tested for x86_64 that installed stripped shared libraries are unchanged by the patch. [BZ #14132] * elf/dl-sysdep.c (__libc_enable_secure): Use rtld_hidden_data_def instead of INTVARDEF. (_dl_sysdep_start): Do not use INTUSE with __libc_enable_secure. * sysdeps/mach/hurd/dl-sysdep.c (__libc_enable_secure): Use rtld_hidden_data_def instead of INTVARDEF. (_dl_sysdep_start): Do not use INTUSE with __libc_enable_secure. * elf/dl-deps.c (expand_dst): Likewise. * elf/dl-load.c (_dl_dst_count): Likewise. (_dl_dst_substitute): Likewise. (decompose_rpath): Likewise. (_dl_init_paths): Likewise. (open_path): Likewise. (_dl_map_object): Likewise. * elf/rtld.c (dl_main): Likewise. (process_dl_audit): Likewise. (process_envvars): Likewise. * include/unistd.h [IS_IN_rtld] (__libc_enable_secure_internal): Remove declaration. (__libc_enable_secure): Use rtld_hidden_proto.
