FYI: fix handle_single_transform_list diagnostic about configure subst

[Alexandre Duret-Lutz]

I'm installing this.  The test for the two flavor of this diagnostic
are subsrc.test and subsrc2.test (they will be made more strict
by the exit-status-check-overhaul-patch I'm preparing).

2003-07-03  Alexandre Duret-Lutz  <address@hidden>

        * automake.in (handle_single_transform_list): Use $var->name
        to print variable in the configure-substitution diagnostic.
        Do not mention the parent when it is the variable itself.
