The fact that the first "random flag" error seemingly comes out before any compiler command is weird but not related to this problem. That happens because our makefile runs a silent (without echoing the command) compiler invocation to build the dependency file. We may possibly want to echo that too, but it doesn't matter that much -- in more realistic scenarios, the error will not be as simple as a missing flag, and the dependency command will succeed, but the error will come from the compilation step.
