No, this bodge isn't needed for __RUMPUSER_XEN__.  The rump kernel
build runs configure with the rump kernel build system which doesn't
see the system's valgrind.h.  I.e., the rump kernel build environment
used for building tools/libxc/ doesn't have the bug that the stubdom
build system has.

There are some __RUMPUSER_XEN__ in libxc but they are just for
selecting the right implementations of various components - in
particular, to make hypercalls directly but use the devices in /dev/
for xenstore and evtchn.  (And for disabling dynamic loading.)

Ian.
