Details:

in Xen 4.0.1 build, there is a line in the Makefile 
-include ../../../../.config 
which follows BSD make convention, should not generate error message even if
the included file does not exist. However, it continues to bug the build
process. The reason is simple. include file will be concat with
include_directories[], and try to see whether we can find it somewhere in the
loop. However, /usr/include/../../../../.config will resolve to /.config even
the original intent is not that since 'cd ..' at '/' will still be '/'. If
there is a '/.config' at '/', then -include will simply fail. 
'../' in Makefile should really be just 'parent dir' and if there is no
parent dir, it should simply FAIL. IMHO.
