re PR bootstrap/31020 (cannot write in </test/gnu/gcc/objdir/prev-gcc/../gcc/./include>)

fixincludes:
	* mkheaders.in: Fix headers for each multilib required.

gcc:
	PR bootstrap/31020
	* configure.ac (CROSS_SYSTEM_HEADER_DIR, build_system_header_dir):
	Define using $${sysroot_headers_suffix}.
	* configure: Regenerate.
	* cppdefault.c (cpp_include_defaults): Make FIXED_INCLUDE_DIR a
	multilib-suffixed directory if SYSROOT_HEADERS_SUFFIX_SPEC
	defined.
	* doc/invoke.texi (-print-sysroot-headers-suffix): Document.
	* gcc.c (print_sysroot_headers_suffix): New.
	(option_map): Include --print-sysroot-headers-suffix.
	(display_help): Mention -print-sysroot-headers-suffix.
	(process_command): Handle -print-sysroot-headers-suffix.
	(do_spec_1): Append multilib directory to include-fixed path if
	sysroot suffixes in use.
	(main): Handle -print-sysroot-headers-suffix.
	* Makefile.in (start.encap): Don't depend on xlimits.h
	(xlimits.h): Remove.
	(stmp-int-hdrs): Don't depend on xlimits.h.  Inline generation of
	limits.h for each multilib in fixinc_list.
	(fixinc_list, s-fixinc_list): New.
	(stmp-fixinc): Depend on fixinc_list.  If not copying headers,
	generate them for each multilib in fixinc_list.
	(stmp-fixproto): Use include-fixed.  Run fixproto for each
	multilib in fixinc_list.
	(mostlyclean): Don't remove xlimits.h.
	(clean): Remove include-fixed.
	(real-install-headers-tar, real-install-headers-cpio,
	real-install-headers-cp): Don't copy include, only include-fixed.
	(install-mkheaders): Depend on fixinc_list.  Don't depend on
	xlimits.h.  Save limits.h files for each multilib in fixinc_list.
	Always save mkinstalldirs.  Preserve ${sysroot_headers_suffix} in
	SYSTEM_HEADER_DIR setting in mkheaders.conf.
