Senthil Kumaran 9f347ea545 reapply the revert made in r83875 
Now the _collections is statically built, the build dependencies are in proper
order and build works fine.

Commit Log from r83874:
Issue 9396.   Apply functools.lru_cache in the place of the
random flushing cache in the re module.
 2010-08-09 07:30:53 +00:00
Raymond Hettinger 31022301b5 Revert 83784 adding functools.lru_cache() to the re module. 
The problem is that the re module is imported by sysconfig
and re needs functools which uses collections.OrderedDict()
but the _collectionsmodule.c code is not yet constructed
at this point in the build.

The likely best solution will be to include _collections
as part of the static build before the rest of the
boot-strapping.
