Fix yet another issue introduced when renaming '-ccc-host-triple' to 

'-target'. The original flag was part of a flag group that marked it as
driver-only. The new flag didn't ever get equivalent treatment. This
caused the '-target' flag to get passed down to any raw GCC invocation.
Marking it as a driver option fixes this and PR11875.
