Require autoconf 2.57 or newer, see TIP 34

	for a detailed explanation of why this is good.
	This will no doubt break the build on some
	platforms, let the flaming begin.

	* tools/configure: Regen with autoconf 2.57.
	* tools/configure.in: Require autoconf 2.57.
	* unix/configure: Regen with autoconf 2.57.
	* unix/configure.in: Require autoconf 2.57.
	Apply AC_LIBOBJ changes from patch 529884.
	* unix/tcl.m4: Ditto.
	* win/configure: Regen with autoconf 2.57.
	* win/configure.in: Require autoconf 2.57.
	Don't subst LIBOBJS since this happens by
	default, this avoids an autoconf error.
