From: Ross Zwisler <ross.zwisler@xxxxxxxxxxxxxxx>
Subject: radix tree test suite: fix mapshift build target
c6ce3e2fe3da ("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.
