Rename cppflags-iterator.mk to libof-iterator.mk, remove extra-modules.mk.

cppflags-iterator.mk no longer has anything to do with CPPFLAGS; all
it does is set libof-$(foo) for a list of files.  extra-modules.mk
does the same thing, but with a different input variable, and doesn't
let the caller control the module.  Therefore, this patch gives
cppflags-iterator.mk a better name, removes extra-modules.mk, and
updates all uses of both.

	* extra-modules.mk: Delete file.
	* cppflags-iterator.mk: Rename to ...
	* libof-iterator.mk: ...this.  Adjust comments.

	* Makerules, extra-lib.mk, benchtests/Makefile, elf/Makefile
	* elf/rtld-Rules, iconv/Makefile, locale/Makefile, malloc/Makefile
	* nscd/Makefile, sunrpc/Makefile, sysdeps/s390/Makefile:
	Use libof-iterator.mk instead of cppflags-iterator.mk or
	extra-modules.mk.

	* benchtests/strcoll-inputs/filelist#en_US.UTF-8: Remove
	extra-modules.mk and cppflags-iterator.mk, add libof-iterator.mk.
