* elf/rtld.c (process_envvars): Don't consider LD_SHOW_AUXV
and LD_DYNAMIC_WEAK if __libc_enable_secure.
If __libc_enable_secure, /etc/suid-debug doesn't exist and
program will be actually run, turn off all debugging.
* sysdeps/generic/unsecvars.h (UNSECURE_ENVVARS): Add LD_DEBUG,
LD_DYNAMIC_WEAK and LD_SHOW_AUXV.
