	* sysdeps/i386/add_n.S [PIC]: Use self-call to avoid generating reloc.
	* sysdeps/i386/sub_n.S [PIC]: Likewise.

	* libc-symbols.h (_elf_set_element) [PIC]: Don't make the element
 	word `const'.

	* Makeconfig (CPPFLAGS, CFLAGS): Fix swapped references to
 	$(foo-$(suffix $@)).

	* manual/Makefile (chapters-incl): Filter out summary.texi.
