With enough parallelism, make will run all the dependencies of
build-all at the same time:
build-all: config-host.h config-all-devices.h $(DOCS) $(TOOLS)
So some of the $(TOOLS) will build before config-host.h is finished.
The object files need to depend on it explicitly. Subdirectories are
OK since they are started from the body of build-all, not its
dependencies.

Maybe a mix of your patch and my patch
(http://patchwork.ozlabs.org/patch/37446/)
would be the best fix for this problem.
It should also be possible to apply both patches.
