Describe the default (each TU produces fully linked executable), and the current limitation (clang can compile to .o, but requires final linking and glue generation to be handled by external build tools). Maybe, describe how to do intermediate linking to a full GPU executable when one builds a library, as we've discussed via emails.

So I guess I should split this between several subsections, or maybe make a new section for it.
