It fails when Excel is installed, for some reason:

    Basic error:
    Type: com.sun.star.uno.RuntimeException
    Message: [automation bridge] unexpected exception in IUnknownWrapper_Impl::invoke ! Message :
    [automation bridge]: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
    macro result for ole_ObjAssignNoDflt.vb
    macro returned:

    C:/cygwin64/home/Tor/lo/64bit-debug/basic/qa/cppunit/test_vba.cxx:155:`anonymous namespace'::VBATest::testMiscOLEStuff
    assertion failed
    - Expression: pReturn->GetOUString() == "OK"
    - Result not as expected

Note that this test returns early if Excel is not installed, so it is
not run effectively performed anyway even in 32-bit builds on most
(any?) Jenkins and tinderbox machines.
