Commit c6ce3e2fe3 ("radix tree test suite: Add config option for map
shift") introduced a phony makefile target called 'mapshift' that ends
up generating the file generated/map-shift.h. This phony target was
then added as a dependency of the top level 'targets' build target,
which is what is run when you go to tools/testing/radix-tree and just
type 'make'.
Unfortunately, this phony target doesn't actually work as a dependency,
so you end up getting:
$ make
make: *** No rule to make target 'generated/map-shift.h', needed by 'main.o'. Stop.
make: *** Waiting for unfinished jobs....
Fix this by making the file generated/map-shift.h our real makefile
target, and add this a dependency of the top level build target.
