Since the TMPDIR change, I have had two random autobuild failures.

Here's the latest one which fails in talloc:

  [32/35] abi_check: lib/talloc/bin/default/lib/talloc/libtalloc.so
  sort: cannot create temporary file in ‘/m/amitay/a/b552249/tmp’: No
such file or directory

It appears as if the TMPDIR has been removed prematurely.  Any ideas?
