For iOS cppunit plugins aren't really "plugins" (shared libraries),
but just static archives. In the real main program of a cppunit app
(such are not yet written), which calls the lo_main() (the
SAL_IMPLEMENT_MAIN() in cppunittester.cxx) we specifically will call
the initialize methods of the CppUnitTestPlugIns that we statically
link to the app executable. Hopefully that will work out as expected.
