Protect against an infloop in python-mode
There appears to be an edge case caused by using `syntax-ppss' in a
narrowed buffer during JIT lock inside of Python triple-quote strings.
Unfortunately it is impossible to reproduce without manually
destroying the syntactic information in the Python buffer, but it has
been observed in practice. In that case it can happen that the syntax
caches get sufficiently out of whack so that there appear to be
overlapping strings in the buffer. As Python has no nested strings,
this situation is impossible and leads to an infloop in

Fix problem with out-of-date dependencies
Problem reported by Robert Marshall in:
http://lists.gnu.org/archive/html/emacs-devel/2017-03/msg00501.html
Although this problem has been with us for a while, the recent
change from Automake to GNU Make exposed it again.
* configure.ac (AUTO_DEPEND): When autodepending, clean out any
leftover dependency and object files, since the previous sources'
dependencies may disagree with the current ones. Reconfiguring
typically needs to force a rebuild anyway.
