We don't make use of xen and when building on Ubuntu 13.04 when

This change disables xen for both -native and target packages but
since it is a PACKAGECONFIG a user could tune this to have xen support
in the target package.

If enabled what dependencies or rdepends does it need? liblzma seems
like it might be one.
I'd like to explain it in more detail, there is no dependency
relationship between them actually, and we don't need set any rdepends
for it.
The root cause is that when xen support is detected by qemu configure,
"-lxenstore" is added to LDFLAGS, but mostly libxenstore.so itself on
host is also compiled as a shared library, so it is linked to liblzma.so
of host path, which will lead a version mismatch with lzma in sysroot.
