Don't scan system includes for dependencies and don't list them
Assume that C and C++ headers found in system paths will not change, so we don't need to tell Make about them, nor do we need to scan their contents either. The previous qmake behavior matched gcc's -M switch; it now matches the -MM switch: -M Instead of outputting the result of preprocessing, output a rule suitable for make describing the dependencies of the main source file. -MM Like -M but do not mention header files that are found in system header directories, nor header files that are included, directly or indirectly, from such a header. This goes hand-in-hand with our use of -isystem to pass system paths to the compiler.
