Quoting of file names is needed in command lines, not in assignments
of values to Make variables.  Make doesn't have a problem with
variable values that include whitespace.  It's the shell that needs
quoting.

So line 266 cannot be the problem, but any command line that uses
$buildlisppath might be.
