[ID 20000410.006] Configure script still too strict about tty

perl 5.6.0 has, in Configure:

	: Sanity checks
	case "$fastread$alldone" in
	yescont|yesexit) ;;
	*)
		if test ! -t 0; then
			echo "Say 'sh Configure', not 'sh <Configure'"
			exit 1
		fi
		;;
	esac

where the check for $fastread being yes and $alldone being cont and
exit to disable the check is relatively new.

This check is still to strict; it should also be disabled in the case
of "./Configure -S".
