This simply follows the scheme we have for other wrappers. It resolves
the current link problem, e.g., `__muldc3 not found`, when std::complex
operations are used on a device.

In "CUDA mode" this should allow simple complex operations to work in
target regions. Normal mode doesn't work because the globalization in
the std::complex operators is somehow broken. This will most likely not
allow complex make math function calls to work properly, e.g., sin, but
that is more complex (pan intended) anyway.
