Fix linking tests with MinGW and Wine imports

[Hans Leidekker]

As described in my mail to wine-devel, this gets us past linking
errors caused by symbols present both in MinGW's C runtime and
Wine's. This may serve as a temporary workaround, because as of
yet MinGW can't be persuaded to not link against it's own C runtime.

Changelog
     Add linker flags for cross compiled tests
