Hi,

22066:eccfdeb41b80 replaced tools/libxc/ia64/aclinux.h with 
xen/include/acpi/platform/aclinux.h.

In fact, the former differs from the latter: the former supports
non-kernel codes, but the latter does not support it because
17814:9af7a535225f removed it.

Thus tools cannot be built on ia64.

This patch adds #ifdef __XEN__ and copies non-kernel support codes in
the former.
