kbuild: fix a bug of C++ host program handling
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 we have a Makefile like this: hostprogs-y := foo foo-cxxobjs := bar.o In this case, foo is treated as host-csingle and Kbuild tries to search non-existing foo.c source.
