I've added a fix for another related issue: the tests would fail to link if libc++ is built only as a DLL.

The auto-linking doesn't look for a dynamic library unless `_DLL` is defined (which I think is done by passing `/MD` to CL), but the test runner doesn't use CL-style commands. This could either be solved by either manually defining that macro or just disabling auto-linking. The test runner already configures the linker correctly so disabling auto-linking seemed like the simplest option.
