 See the discussion on #812:
 http://bind10.isc.org/ticket/812#comment:10
 (see the "src/lib/util/unittests/Makefile.am" part)

 Currently there are complicated subtle mutual dependencies between
 various components of libutil as briefly mentioned in its Makefile.am:
 {{{
 SUBDIRS = . tests unittests io
 # The io/tests is hack, because otherwise we can not order these
 directories
 # properly. Unittests use io and io/tests use unittest.
 }}}

 The troubles we've seen seem to suggest we shouldn't try to solve
 these dependency issues with subtle and tricky build ordering.  IMO we
 should clarify the dependency and reorganize things so that
 dependencies will be one way.
