Configuring GCC for obsolete targets works as long as build = host.
When it isn't, --enable-obsolete is not passed down to the additional
build configure started by gcc/configure, used to generate
auto-build.h.  The build configure fails and we end up without a
auto-build.h, but the host configure proceeds, so we only get a fatal
failure much later, when make realizes auto-build.h is not there and
there's no rule to create it.

This patch gets the host configure to fail when the build configure
does, leaving the temporary build configure dir behind for
investigation.  It also arranges for --eanble-obsolete to be passed
down to the build configure.

Alas, the latter triggered a warning in the build configure because
--enable-obsolete is not a recognized configure option.  That's not
reported in the host configure because of the
--disable-option-checking passed by the top-level configure, so I
arranged for that to be passed down to the build configure as well.

Finally, since my initial suspicion when investigating this failure
was that auto-build.h had been removed after configuration and there
was no rule to rebuild it, I'm adding rules to gcc/Makefile to get it
created or updated as needed.  Since it is configure that creates it,
as run by e.g. config.status --recheck, and config.status is created
after auto-build.h, I've made config.status depend on auto-build.h,
and added a dummy rule to create auto-build.h.  This would normally
not be enough to create a header when needed, but since Makefile
depends on config.status, and make first updates Makefile, it ends up
working, as long as nothing else that Makefile depends on requires
auto-build.h but not config.status.  The config.status dependency and
the auto-build.h rule are only enabled in the cases in which
auto-build.h is actually used, namely when build != host.

	(CP_PARSER_FLAGS_CONSTEVAL): New.
	(cp_parser_skip_balanced_tokens): New forward declaration.
	(cp_parser_lambda_declarator_opt): Handle ds_consteval.  Set
	current_binding_level->immediate_fn_ctx_p before parsing parameter
	list if decl-specifier-seq contains consteval specifier.
	(cp_parser_decl_specifier_seq): Handle RID_CONSTEVAL.
	(cp_parser_explicit_instantiation): Diagnose explicit instantiation
	with consteval specifier.
	(cp_parser_init_declarator): For consteval or into flags
	CP_PARSER_FLAGS_CONSTEVAL.
	(cp_parser_direct_declarator): If CP_PARSER_FLAGS_CONSTEVAL, set
	current_binding_level->immediate_fn_ctx_p in the sk_function_parms
	scope.
	(set_and_check_decl_spec_loc): Add consteval entry, formatting fix.
	* call.c (build_addr_func): For direct calls to immediate functions
	use build_address rather than decay_conversion.
	(build_over_call): Evaluate immediate function invocations.
	* error.c (dump_function_decl): Handle DECL_IMMEDIATE_FUNCTION_P.
	* semantics.c (expand_or_defer_fn_1): Use tentative linkage and don't
	call mark_needed for immediate functions.
	* typeck.c (cxx_sizeof_or_alignof_expr): Likewise.  Formatting fix.
	(cp_build_addr_expr_1): Reject taking address of immediate function
	outside of immediate function.
	* decl.c (validate_constexpr_redeclaration): Diagnose consteval
	vs. non-consteval or vice versa redeclaration.  Use
	SET_DECL_IMMEDIATE_FUNCTION_P if new_decl is immediate function.
	(check_tag_decl): Use %qs with keyword string to simplify translation.
	Handle ds_consteval.
	(start_decl): Adjust diagnostics for static or thread_local variables
	in immediate functions.
	(grokfndecl): Call sorry_at on virtual consteval.  Use %qs with keyword
	to string to simplify translation.  Diagnose consteval main.  Use
	SET_DECL_IMMEDIATE_FUNCTION_P for consteval.
	(grokdeclarator): Handle consteval.  Use %qs with keyword strings to
	simplify translation.  Use separate ifs instead of chained else if
	for invalid specifiers.  For constinit clear constinit_p rather than
	constexpr_p.
	* constexpr.c (find_immediate_fndecl): New function.
	(cxx_eval_outermost_constant_expr): Allow consteval calls returning
	void.  Diagnose returning address of immediate function from consteval
	evaluation.
	(fold_non_dependent_expr_template): Add OBJECT argument, pass it
	through to cxx_eval_outermost_constant_expr.
	(fold_non_dependent_expr): Add OBJECT argument, pass it through to
	fold_non_dependent_expr_template.
	(fold_non_dependent_init): Adjust fold_non_dependent_expr_template
	caller.
	* method.c (defaulted_late_check): Adjust diagnostics for consteval.
	* lambda.c (maybe_add_lambda_conv_op): Copy over
	DECL_DECLARED_CONSTEXPR_P and DECL_IMMEDIATE_FUNCTION_P bits from
	callop to both artificial functions.
	* init.c (build_value_init): Don't do further processing if
	build_special_member_call returned a TREE_CONSTANT.  Formatting fix.
