Subject: configure: allow variables to contain quotes.

* configure: When generating the assignment that stores the
value of the command line variable into the corresponding
shell variable, interpolate $val between single quotes in such
a way that single quotes occurring in $val are replaced by the
pattern '\''. Thus, variables may contain any character
whatsoever.
