Indeed, I did this on commit.

Perhaps Andrew is running "cd tools ; ./configure"?

In http://lists.xen.org/archives/html/xen-devel/2014-07/msg03156.html I
posited that nobody would be doing that (even going so far to doubt that
it worked) but if Andrew is doing it then clearly I was wrong and we
will need to rethink the approach.

If we need to support direct invocation of "sub" configure then the only
approach which comes to my mind is to generate per-subsystem Paths.mk,
e.g. in each of the sub-configures do:
along with the other stuff[0] and adjusting the Makefile to use it,
substituting Tools as needed for other subsystems of course.

I think you will also need to -include rather than include so that make
clean et al work on an unconfigured tree. There is existing logic in the
all the (I think) right places to deal with non-clean targets needing
configure to have been run.

BTW, I noticed the opposite problem to Andrew, which is that Paths.mk is
not removed by "make clean".


 says that the : syntax lets you override the input.
