make sure "." is listed before tests in SUBDIRS to ensure things to be tested are ready when doing tests.  specifically, the immediate 'make check' after "configure" would fail without these changes.

this may not be super minor, but I think it's still quite trivial and isn't worth spending others's time for review.  so I'll skip review.  If I broke something buildbot will tell it to us.
