Looks like the changes to tools/include/xen/ population have
increased the chances of running into the race (or some similar
one) reported by Olaf in "races in toolstack build":

Obviously recursing into tools/include/ needs to precede any other
recursion underneath tools/. Or wait - this is a bogus 2nd recursion
into tools/include/, there's an appropriate one very early in the
build. I guess it's
