The kernel now supports debug registers and I do have patches to make use of
them in my queue. The fact that QEMU expects internal code to provide certain
functions depending on some random #define in a header file is just plain
broken though.
Hence we want an intermediate quick fix to at least get upstream buildable
again and then implement the real deal.
