This works for the .o files. Now, how to make the .a files
(i.e. aggregation) and how to make the .h_prims files (header
generation which messes up GCC's dependency generation.
The latter is the real problem. What would solve it is to generate a
dependency file of the .d file itself, and generate the deps in two
What seems to work is -MM which skips system files.
-MG In conjunction with an option such as -M requesting dependency
generation, -MG assumes missing header files are generated files
and adds them to the dependency list without raising an error.
The dependency filename is taken directly from the "#include"
directive without prepending any path. -MG also suppresses
preprocessed output, as a missing header file renders this
That was easy!
