Agreed. Also, removing things is often surprisingly hard.
Let's keep things simlpe, get this compilation mode to the point where it's practically usable, see what we really want/need, and then make those common cases the default or easier to use.

As far as libdevice is concerned, it's only needed for sources that use CUDA headers, as those map the standard math functions to their implementations in libdevice. Stand-alone sources should not need it. We should also be able to compile libdevice.bc into a  libdevice.o and then link with it, if needed, during the final executable link phase.
