When cross-compiling, if no kernel_dir was specified, then the kernel
modules were still being compiled for the build machine. Fix this by
only building modules on cross-compile when we have a kernel_dir value
set. Print out a message indicating why we are skipping kernel
compilation, and in case that the headers for kernel compile are not
found, print a warning instead of erroring out.
