	$(exec_prefix)/sbin.
	(rtld-version-installed-name): New, default as
	ld-$(version).so.

	* Makefile (install): Call `$(common-objpfx)elf/ldconfig -d'

	$(make-shlib-link) for symlink.

	(install-no-libc.a-nosubdir): Add
	install-rootsbin-nosubdir.

	substitute.

	* elf/Makefile (others, install-rootsbin): New, set to
	ldconfig.

	($(slibdir)/$(rtld-version-installed-name)): New.
	($(slibdir)/$(rtld-installed-name)): Depend on

	$(make-shlib-link) for symlink.

	* sunrpc/xdr.c (xdr_string): Return FALSE if sp == NULL
	while XDR_ENCODE.

	* sysdeps/unix/sysv/linux/a.out.h: Use #include_next for
	glibc internals.
