Fix the test logic

The DESTDIR variable mentions ${TESTDIR}, ${ARCHITECTUREDIR},
${CONFIGURATIONDIR}, which is required because tests looks like

  test -x ${DESTDIR}${BINDIR}/wordcount
  test -f ${DESTDIR}${MANDIR}/man1/wordcount.1.gz

If DESTDIR does not mention the aforementioned variables, a test can
find files installed by some previous tests and return a false
positive.
