        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.
