This is a hack (to call it something).  Can we have a proper fix for
this?  Just putting that files under tcg-libobj-y (or something like
that), and add it only to some targets.  There is (another similar bad
hack) on qemu-kvm.git to disable them for ia64.  Can we get something
saner here?

Later, Juan.

PD. No, this is not xen specific, disabling compilation of tcg on qemu
    is basically imposible.
