One issue is the usleep problem which is unimplemented in nvptx newlib,
that might get fixed through declare variant directive (have parsing for
that roughly done, but not more than that so far).
Another thing is unimplemented link support in NVPTX offloading, that just
needs work.

include <cuda.h> or even link against -lcuda, if they don't work with the
--without-cuda-driver setup, would be just UNSUPPORTED, otherwise it is too
much clutter.
