The configure script does not check if junit exists and/or is usable. This causes `make
check` to fail with a long error log ending with:
<output>
../../../../cacao-staging/tests/regression/base/TestPatcher.java:581: error: The method
fail() is undefined for the type TestPatcher
        fail();
        ^^^^
200 problems (198 errors, 2 warnings)
make[3]: *** [build] Error 1
make[3]: Leaving directory `/home/zapster/cacao/cacao-build/tests/regression/base'
make[2]: *** [check-recursive] Error 1

</output>
This might be confusing to some users. configure should emit a warning.
