	* configure, configure.in (has_ldconfig): New substitute.

	* sysdeps/unix/sysv/linux/configure.in (has_ldconfig): New,
	check if $srcdir/elf/ldconfig.c exists.

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

	* Makefile (install): Call `$(common-objpfx)elf/ldconfig -d'
	only if $(cross-compiling) is no and $(build-shared) is yes.

	* Makerules (make-shlib-link): New macro.
	($(slibdir)/libfoo.so.$(libfoo.so-version)): Use
	$(make-shlib-link) for symlink.
	(install-rootsbin, install-rootsbin-nosubdir): New.
	(install-no-libc.a-nosubdir): Add
	install-rootsbin-nosubdir.

	* Rules (others): Add $(install-rootsbin).

	* config.make.in (rootsbindir): New.

	* configure, configure.in (libc_cv_rootsbindir): New
	substitute.

	* elf/Makefile (others, install-rootsbin): New, set to
	ldconfig.
	(+link): New for static linking.
	($(slibdir)/$(rtld-version-installed-name)): New.
	($(slibdir)/$(rtld-installed-name)): Depend on
	$(slibdir)/$(rtld-version-installed-name) and use
	$(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.

	* sysdeps/unix/sysv/linux/configure.in (libc_cv_rootsbindir):
	New, set to "/sbin" if "$prefix" == "/usr".
