This series is part of the single binary effort.
All accelerator will share their per-vCPU context in
an opaque 'accel' pointer within the CPUState.
First handle HAX/NVMM/WHPX/HVF. KVM and TCG will follow
as two different (bigger) follow-up series.

The same command is used to generate the value of both $(TARGET_ARCH)
and $(SRCARCH), as $(ARCH) is an alias for $(XEN_TARGET_ARCH).
