-MM and -MMD are not ignoring #include <xx.h> files

Hi Tim,

What's going on is that you are using -I instead of -idirafter.

-I adds a path to the general include path list.

-idirafter adds a path to the system include path list.

The -MM and -MMD filter out the system include path list, not the general 
include path list.
