If gawk is not installed, the build reports "gawk not found", but then 
fails with strange errors about kvm.h having the wrong version, mismatch 
between kernel and userland, and even more resulting errors later on. 
This sent me off the wrong trail.

Please:

   1. Check that all apps used in the build process are checked in
      configure and reported right there. Esp. gawk in this case.
   2. Improve the version check to not say "version mismatch" when the
      kvm.h file does not exist at all or is entirely empty, i.e.
      KVM_API_VERSION is empty.
