  I was about to report something like this myself this week.  Too often
 I install Xen on a new host and miss a dependency due to carelessness.

  Please find a patch below to "make world" which first runs "make tools/check"
 hopefully making sure that all dependencies are present and detected
 early.

  (Most frustrating is missing libssl, or libz, which is only otherwise
 detected right at the end of a kernel build.)
