This patch corrects a problem in which GDB ignores the debug info for
offload kernel entry functions because they're represented as nested
functions inside a function that does not exist on the accelerator
device (only on the host).
Apparently I had a bug in this patch that only showed up after another
clean build (not sure what was different).
This patch fixes it. Apparently the flag_generate_offload was wrong.
Committed to OG10. I will squash the two patches when they go to mainline.

Correct fix offload dwarf info
The previous patch wasn't quite right, apparently. Somehow the behaviour
changed after another clean build? This tweak fixes it.
This patch should be squashed with fdcb23540a2 to go to mainline.
