Without changing anything no.
But if xen sub-directory is renamed yes.

As there is no easy way to build xen hypervisor out of tree (I might be wrong 
here !) I found a solution using cp -rs from xen subdir in a xen-build1 
xen-build2 etc this way I can check build for x86 and arm without cleaning.

Without the patch, the sources are actually compiles with an include path 
containing xen/../xen as a result of using XEN_ROOT which does not allow to 
rename xen subdirectory.
As it was the only place in which XEN_ROOT was used for include paths, this is 
normalising the paths.
