This patch adds logic to create jobs for OpenMP offloading actions by:
 - tuning the jobs result information to use the offloading prefix even for (device) linking actions.
 - replacing the device inputs of the host linking jobs by a linker script that embed them in the right sections.

With this patch, it is possible to produce a fully functional binary using OpenMP offloading capabilities with no separate compilation.
