        * configure.ac (CFLAGS_FOR_TARGET, CXXFLAGS_FOR_TARGET): Compute here.
        * configure: Regenerate.

        * Makefile.def: Define stage_libcflags for all bootstrap stages.
        * Makefile.tpl (BOOT_LIBCFLAGS, STAGE2_LIBCFLAGS, STAGE3_LIBCFLAGS,
        STAGE4_LIBCFLAGS): New.
        (CFLAGS_FOR_TARGET, CXXFLAGS_FOR_TARGET): Subst from autoconf, without
        $(SYSROOT_CFLAGS_FOR_TARGET) and $(DEBUG_PREFIX_CFLAGS_FOR_TARGET).
        (BASE_TARGET_EXPORTS): Append them here to C{,XX}FLAGS.
        (EXTRA_TARGET_FLAGS): Append them here to {LIB,}C{,XX}FLAGS.
        (configure-stage[+id+]-[+prefix+][+module+]): Pass stage_libcflags
        for target modules.  Don't export LIBCFLAGS.
        (all-stage[+id+]-[+prefix+][+module+]): Pass stage_libcflags; pass
        $(BASE_FLAGS_TO_PASS) where [+args+] was passed, and [+args+] after
        the overridden CFLAGS_FOR_TARGET and CXXFLAGS_FOR_TARGET.
        (invocations of `all'): Replace $(TARGET_FLAGS_TO_PASS) with
        $(EXTRA_TARGET_FLAGS), $(FLAGS_TO_PASS) with $(EXTRA_HOST_FLAGS).
        * Makefile.in: Regenerate.
