My question would be where in the world is the -fno-pie stuff coming
from.  It's also not clear where mkoffload is being called within c#5
(presumably via the linker plugin) AFAICT we don't get the command line
for that.  -v  or -Wl,-v probably would have helped.  It's difficult to
know if HJ's patch is correct or not given the missing bits of information.

But I'm willing to trust HJ here.  I'll ack the patch for the trunk.
You or HJ can go ahead and install it.

THe bigger question about the viability/usability of MIC is punted ;-)
