I will push this in a couple of days if there is not objection.

To declare prerequisites common to all the tests, we now prefer to
use the special `check_DATA' and `check_SCRIPTS' variables rather
than "lazy" dependency declaration like "$(TEST_LOGS): DEPS ...";
this because the latter, allowing run-time overriding of the
TEST_LOGS variable, turned out to be subtly incomplete in some
situations involving non-trivial inter-test dependencies. For
example, if the user issued a:
make check TESTS=libtool.test
before the `defs-static' file was created (either explicitly or
implicitly), a spurious errors followed, along these lines:
1. $(TEST_LOGS) got dynamically defined to `libtool.log';
2. make saw that, in the Makefile, `libtool.log' was explicitly
declared depending on `libtool-macros.log' and `defs-static';
3. somehow, make considered the dependency on `libtool-macros.log'
*before* considering the one on `defs-static' (which BTW is
perfectly legitimate on make's part);
4. to satisfy such a dependency, make set out to execute the
test `libtool-macros.test' in order to create the file
`libtool-macros.log';
5. since `libtool-macros.log' was *not* in $(TEST_LOGS), it
didn't appear to depend on the `defs-static' file, so make
didn't consider necessary to build `defs-static' before
running the `libtool-macros.test' script;
6. but that script sources `./defs-static' in order to work;
thus the test `libtool-macros.test' failed spuriously.
* tests/Makefile.am ($(TEST_LOGS)): Remove explicit declaration
of dependency on the required files/scripts; instead use ...
(check_SCRIPTS, check_DATA): ... these new variables.
