* elf/elf.h (AT_SECURE): New macro. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Grok it, set __libc_enable_secure. (_dl_show_auxv): Add AT_SECURE to name table. * elf/dl-support.c (_dl_aux_init): Grok AT_SECURE, set __libc_enable_secure and __libc_enable_secure_decided. * sysdeps/unix/sysv/linux/ldsodefs.h [__ASSUME_AT_SECURE] (HAVE_AUX_SECURE): Define it. * sysdeps/unix/sysv/linux/kernel-features.h [__LINUX_KERNEL_VERSION >= 132425] (__ASSUME_AT_SECURE): Define it.
