This "regression" is in fact a lost race, due to the bizarre reentry
into the kernel build system, while attempt to build the remus kernel

I seem to remember a previous discussion of this, with a suggestion
that this part of the build should be disabled in xen-unstable pending
a more sane arrangement.  But I couldn't find the patch in

It seems to me that the patch below is probably about right.  Any
contrary opinions ?
