Florian Weimer a014cecd82 Always enable pointer guard [BZ #18928]
Honoring the LD_POINTER_GUARD environment variable in AT_SECURE mode
has security implications.  This commit enables pointer guard
unconditionally, and the environment variable is now ignored.

        [BZ #18928]
        * sysdeps/generic/ldsodefs.h (struct rtld_global_ro): Remove
        _dl_pointer_guard member.
        * elf/rtld.c (_rtld_global_ro): Remove _dl_pointer_guard
        initializer.
        (security_init): Always set up pointer guard.
        (process_envvars): Do not process LD_POINTER_GUARD.
