I suggest you rename the files to another extension, ie *.ccfg, and we side step
the issue for now. With Sebastian's build system change coming it may be simpler
If you want to build now I would look for the include spot for the `*.cfg` in
the Makefiles to see if some Makefile magic can detect a clang compiler and
change the extension.
