	($(common-objpfx)sysd-dirs): Target removed.  Don't include it.
	($(common-objpfx)sysd-sorted): Rewritten to feed Depend and Subdirs
	files together to gen-sorted.awk, and $(subdirs) via -v.
	(subdirs): Remove magic reordering for mach and hurd.
	* scripts/gen-sorted.awk: Use subdirs from command line.
	Process Subdirs and Depend files directly.
	Let Subdirs files use "first dir" and "inhibit dir".
	Always move elf to the end of the list.
	* hurd/Depend: New file.
	* sysdeps/mach/Subdirs: Use "first mach".

	* Makefile (dist-separate): Remove linuxthreads.
	(dist-separate-linuxthreads): Variable removed.
	(glibc-%.tar rule): Use $(sysdeps-add-ons).

	* Makerules ($(common-objpfx)Versions.v.i): Use $(subdirs),
	not $(all-subdirs).
	(sysdep-makefiles): Use $(sysdirs).
	(sysdirs): Remove export.
	($(+sysdir_pfx)sysd-rules): Handle absolute directory names in
	$(config-sysdirs).
	(+sysdir_pfx): Variable removed.
	(sysd-rules): Use $(common-objpfx) in place of it.
	(sysdirs): Variable moved to ...
	* Makeconfig (sysdirs): ... here.
	Handle absolute directory names in $(config-sysdirs).
	(full_config_sysdirs): Variable removed.
	* csu/Makefile: Use $(sysdirs) in vpath directive.
	* math/Makefile (ulps-file): Use $(sysdirs).
	* sysdeps/gnu/Makefile (errlist-c): Likewise.
	($(objpfx)errlist-compat.c): Likewise.
	* Makeconfig (all-Subdirs-files): Likewise.
	($(common-objpfx)config.status): Likewise.

	* configure.in (sysnames): Handle absolute add-on directory names.
	(sysdeps_add_ons): New variable, AC_SUBST it.
	Compute which add-ons contributed sysdeps directories.
	* configure: Regenerated.
	* config.make.in (sysdeps-add-ons): New substituted variable.
	* Makerules (+sysdep_dirs, +sysdep-includes): Variables moved ...
	* Makeconfig: ... to here.
	(+sysdep_dirs): Append $(sysdeps-add-ons) here.
	(+includes): Remove $(objpfx) include, already in $(+sysdep_dirs).
	Remove $(includes).
	(sysdep-makeconfigs): Use $(+sysdep_dirs).
	($(common-objpfx)shlib-versions.v.i): Likewise.

	* Makeconfig: Remove hair to set Makeconfig-add-on.

	* sysdeps/unix/Makefile (sysdirs): Remove export.
	(asm_CPP): Variable removed.
	($(common-objpfx)sysd-syscalls): Pass them directly for the script.

	* sysdeps/posix/Makefile: New file.
	* Makerules (L_tmpnam, TMP_MAX, L_ctermid, L_cuserid): Set non-posix
	values here with ?=.

	* stdlib/gen-mpn-copy: File removed.
