Subject: [PATCH 34/45] Fix broken Xen support in configure.ac

Commit 2cf7cb9a "kexec: implemented XEN KEXEC STATUS to determine
if an image is loaded" added configure-time detection of the
kexec_status() call, but in doing so had the unintended side
effect of disabling support for Xen altogether due to the
missing HAVE_LIBXENCTRL=1. This corrects the broken behavior
while still maintaining the original intention of detecting
support for kexec_status() call.
