Fix parallel testsuite run with Zsh. This change deals with a Zsh incompatibility in the handling of the special shell variable `$0' in sourced files; this incompatibility used to cause utter breakage when the Automake testsuite was run in parallel mode with Zsh as the $(TEST_LOG_COMPILER). For more information, please refer to the thread "Fix parallel testsuite run with zsh" on automake-patches, dated 2010-12-22: <http://lists.gnu.org/archive/html/automake-patches/2010-12/msg00135.html> This change works around the problems described above for Zsh 4.3 or later, and offers better error messages (instead of random failures) for earlier Zsh version. * tests/README (Supported shells): When describing the manual workaround about the Zsh incompatibility in the handling of `$0', tell that it is now needed only with Zsh versions preceding 4.3. Done also some minor rewordings. * tests/defs-static.in ($argv0): New variable, offers a workaround for the Zsh incompatibility in the handling of `$0'. Abort if that variable cannot be correctly set (can happen only in older Zsh version). * tests/defs ($me): Define using `$argv0', not `$0'.
