constructs generated by autoconf do not work in the ash shell

[Mark Hobley]

Binary package hint: autoconf2.64

Some versions of the ash shell will not allow redirection to a stream number held in a variable:

  # This construct does not work in some versions of the ash shell
  echo $1 >&$2

The autoconf tool sometimes generates scripts using this construct, The following is an example of a code snippet using this construct in a configure script:

  if test "$3"; then as_lineno=${as_lineno-"$2"}
    as_lineno_stack=as_lineno_stack=$as_lineno_stack
    $as_echo "$as_me:${as_lineno-$LINENUM}: error: $1" >&$3
  fi

(I think this is coming from the _AS_ECHO_LOG macro).
