Libguestfs - May 2015 - [PATCH 2/2] configure: simplify check for oUnit v2

Not actually useful, as TESTS defines the tests, and it breaks when
oUnit is not available (as it tries to build an oUnit-based unit test).

Instead of parsing the version, try to look for the OUnit2 module within
the oUnit package.

I don't think this is spurious (although it doesn't do very much).
Automake wants us to list all built scripts in a check_SCRIPTS rule,
of which this is one.  See section 9.1 Executable Scripts in the
automake info file.

It probably does need to be changed to:

check_SCRIPTS if HAVE_OCAML_PKG_OUNIT
check_SCRIPTS += common_utils_tests
endif

This one is OK, ACK.

This is somehow confusing, as check_SCRIPTS and check_PROGRAMS seem to
be defined as the scripts/programs needed by the tests (those in TESTS),
although it says they can be added to TESTS...
Add to that that common_utils_tests is not really a script (like a
shell/Python/etc would be), and it's somehow that due to not being built
with automake.

I've just sent a couple of patches which, in the end, link the two tests
in mllib using automake.

Right, although with my patches this is now check_PROGRAMS.
