Windowing system distributor `The X.Org Foundation', version

System Description:     NAME=Gentoo

When configure is called with an option containing backslashes, for
example:

   configure --program-transform-name="s/^\(emacs\)-[0-9].*-\1/\1/"

then these backslashes will be interpreted as escapes, leading to the
following result in lisp variable system-configuration-options:

   --program-transform-name=s/^(emacs)-[0-9].*-^A/^A/

(where ^A is really C-a, ASCII 0x01).

The patch below fixes the problem for me.
