----------------------------------+-----------------------------------------
 Currently the unit tests test_util_spawn_background_* assume that they are
 run from the Tor build directory (so as to find test-child). This is not
 the case when running make distcheck, so the test will fail. The path to
 test-child can be found through dirname(argv![0])/../test-child, but unit
 tests don't have access to argv![0]. Therefore one solution is to use
 autoconf to find the Tor build directory and base the path on this.
