The comment claims: C++ executables compiled from at least one .cc file and zero or more .c files But C++ executables with zero .c file fail in build. For example, assume Makefile is like this: hostprogs-y := foo foo-cxxobjs := bar.o In this case, foo is treated as host-csingle and Kbuild searches foo.c source.
