* cppflags-iterator.mk (CPPFLAGS-$(cpp-src)): Variable removed.

Browse Source 
instead of += to append, to be sure $(lib) gets expanded at defn time.
	(libof-$(cpp-src)): New variable, define this instead.
	* extra-lib.mk (cpp-srcs-left): Reduce duplication in include setup.
	(lib): Don't use override.
	(CPPFLAGS-$(lib)): New variable, put -D's here.
	* Makeconfig (CPPFLAGS): Use basename fn for CPPFLAGS-basename.
	Also add $(CPPFLAGS-LIB) before the file-specific flags, for each
	LIB found by $(libof-*) for basename, target, or source.
	* Makerules (CPPFLAGS-nonlib): New variable.
	* nscd/Makefile (lib): Set to nonlib when using cppflags-iterator.mk.
	* locale/Makefile (lib): Likewise.
	* sunrpc/Makefile (lib): Likewise.

	* sysdeps/unix/sysv/linux/fpathconf.c (LINUX_LINK_MAX): Move macro ...
	* sysdeps/unix/sysv/linux/linux_fsinfo.h (LINUX_LINK_MAX): ... here.
	* sysdeps/unix/sysv/linux/pathconf.h: New file.
	(statfs_link_max): New function, guts from fpathconf.c.
	* sysdeps/unix/sysv/linux/fpathconf.c: Rewritten using that.
	* sysdeps/unix/sysv/linux/pathconf.c (__pathconf): Likewise.
	* sysdeps/unix/sysv/linux/alpha/pathconf.c (__pathconf): Rewritten
	to use the linux/pathconf.c code by #include rather than duplication.
