Add #[link_type="object"] to link against object files

[erickt]

I need to write some wrapper functions in C for my zeromq bindings. It seems a bit heavyweight to create a shared library just to link these functions in, so I'm cheating and putting my .o files in the link_args for the zmq native mod. I'd rather put these functions in their own module rustzmq and just label it with #[link_type="object"], and have rustc automatically link against rustzmq.o.

Could you put your wrapper functions in a static library?
