Update.
* elf/elf.h: Add dynamic tag definitions for prelinking.
* elf/rtld.c (process_envvars): Avoid using array of string pointers.
Rewrite code to remove environment varables for SUID binaries.
Small optimization in LD_PROFILE handling.
* sysdeps/generic/unsecvars.h: Adjust format for process_envvars
changes.
* sysdeps/unix/sysv/linux/i386/dl-librecon.h: Likewise.
* sysdeps/generic/dl-sysdep.c: Don't initialize _dl_cpuclock_offset.
