[Xen-devel] [v3][PATCH] tools/hvmloader: link errno.h from xen internal



We need to act on some specific hypercall error numbers, so
require the hypervisor view on the errno.h value rather than
just the build environment's number. So here link this headfile
from xen.

v3:

* Address Jan's two comments
  The file name would seem quite right to be used as dependency here.
  subdirs-all should depend on errno.h

v2:

* CCed more tools MAINTAINERS
* Rephrase long log
* Remove this line '@rm -rf errno.h' since we always force link
* Drop including this head file in util.h directly
