Subject: [PATCH] Expose automated tests under "make check"

The following unit tests can be run automatically without specifying any
user-provided arguments:
hrg_test lex_test multi_thread nums_test regex_test token_test

Fix up the Makefiles to expose the ability to run these tests via "make
check" or "make test", since it is currently broken (exposed at the top
level, but missing the "test" target in testsuite/).
