If the designated pathname by XEN_PATH doesn't exist, it's easy to find
such problem by simply make which should fail immediately since required
header files don't exist by following wrong symbolic link. Then you can
easily "make clean" again and then "make XEN_PATH=right_path_name" to
try it out finally. In this special case here, even compiling first *.c
file will give you error since asm-xsi-offsets.h is required as a
fundamental header file. ;-)

Thanks,
Kevin
