    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.
