configure.in (CONFIGURED_BISON, [...]): Remove "CONFIGURED_" from the AC_CHECK_PROGS invocation.

toplevel:
2005-12-05  Paolo Bonzini  <bonzini@gnu.org>

	* configure.in (CONFIGURED_BISON, CONFIGURED_YACC, CONFIGURED_M4,
	CONFIGURED_FLEX, CONFIGURED_LEX, CONFIGURED_MAKEINFO): Remove
	"CONFIGURED_" from the AC_CHECK_PROGS invocation.  Move below.
	Find in-tree tools if available.
	(EXPECT, RUNTEST, LIPO, STRIP): Find them and substitute them.
	(CONFIGURED_*_FOR_TARGET): Don't set nor substitute.
	(*_FOR_TARGET): Set them with GCC_TARGET_TOOL.
	(COMPILER_*_FOR_TARGET): New.
	* Makefile.tpl (HOST_EXPORTS): Add *_FOR_TARGET symbols that gcc needs.
	(BASE_TARGET_EXPORTS): Use COMPILER_*_FOR_TARGET symbols.
	(CONFIGURED_*, USUAL_*): Remove.
	(BISON, YACC, FLEX, LEX, M4, MAKEINFO, EXPECT, RUNTEST, LIPO,
	STRIP): Use autoconf substitutions.
	(COMPILER_AS_FOR_TARGET, COMPILER_LD_FOR_TARGET,
	COMPILER_NM_FOR_TARGET): New.
	(EXTRA_HOST_FLAGS): Pass LIPO and STRIP.

	(all): Make all-host and all-target in parallel.
	(do-[+make_target+], do-check, install, [+compare-target+]): Ensure
	that $$r and $$s are set before invoking a recursive make.
	(stage[+id+]-bubble): Likewise, and invoke the comparison at the end.
	([+bootstrap-target+]): Inline most of the `all' target.
