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.
