* elf/Versions [GLIBC_PRIVATE]: Export __pointer_chk_guard if defined.
* elf/rtld.c: Define __pointer_chk_guard_local and if necessary __pointer_chk_guard. (_rtld_global_ro): Initialize _dl_pointer_guard. (dl_main): Initialize __pointer_chk_guard_local and either __pointer_chk_guard or TLS value if necessary. (process_envvars): Recognize and handle LD_POINTER_GUARD. * sysdeps/generic/ldsodefs.h (rtld_global_ro): Add _dl_pointer_guard. * sysdeps/i386/__longjmp.S: Use PTR_DEMANGLE for PC if defined. * sysdeps/x86_64/__longjmp.S: Likewise. * sysdeps/i386/bsd-_setjmp.S: Use PTR_MANGLE for PC if defined. * sysdeps/i386/bsd-_setjmp.S: Likewise. * sysdeps/i386/setjmp.S: Likewise. [IS_IN_rtld]: Avoid call to __sigjmp_save. * sysdeps/i386/setjmp.S: Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h: Define PTR_MANGLE and PTR_DEMANGLE. * sysdeps/unix/sysv/linux/x86_64/sysdep.h: Likewise. * sysdeps/i386/elf/setjmp.S: Removed. * sysdeps/i386/elf/bsd-setjmp.S: Removed.
