Update to 0.14:

Experimental version released on June 14th, 2011.

* Added a pkg-config file for atf-sh and an aclocal file to ease the
  detection of atf-sh from autoconf scripts.

* Made the default test case body defined by atf_sh fail.  This is to
  ensure that test cases are properly defined in test programs and helps
  in catching typos in the names of the body functions.

* PR bin/44882: Made atf-run connect the stdin of test cases to /dev/zero.
  This provides more consistent results with "normal" execution (in
  particular, when tests are executed detached from a terminal).

* Made atf-run hardcode TZ=UTC for test cases.  It used to undefine TZ, but
  that does not take into account that libc determines the current timezone
  from a configuration file.

* All test programs will now print a warning when they are not run through
  atf-run(1) stating that this is unsupported and may deliver incorrect
  results.

* Added support for the 'require.files' test-case property.  This allows
  test cases to specify installed files that must be present for the test
  case to run.

And, while doing this, add a buildlink3.mk file.
