Message 70114 - Python tracker

This bug should be re-opened. The patch to configure.in wasn't quite
right. I'm attaching a slight fix. `autoconf`ing removes one level of
square brackets in the 'sed' command to create $tgt.

(Q about the issue tracker: I'm unable to change the "Status" field on
this bug. I'm guessing that is "by design", right? I.e., only certain
people have the privs to change bug status?)
