No.  `--target-code-only' is set if you are generating *only* target code,
not object code.  If you are generating target code and then compiling
that target code to object code, then `--target-code-only' will not be set.

You would need to use something like

		{ bool__or_list([GenerateDependencies, MakeInterface,
			MakePrivateInterface, MakeShortInterface,
			MakeOptimizationInt, MakeTransOptInt,
			ConvertToMercury, TypecheckOnly, ErrorcheckOnly

Although ideally it should be abstracted out into a sub-routine.

Or alternatively you could add a new compiler option, for internal
use only, and set it appropriately in handle_options.m.
