[ Upstream commit 41c240099fe09377b6b9f8272e45d2267c843d3e ]

The tools/testing/selftests/vm/Makefile uses the variable TARGETS
internally to generate a list of platform-specific binary build targets
suffixed with _{32,64}. When building the selftests using its own
Makefile directly, such as via the following command run in a kernel tree:

One receives an error such as the following:

make: Entering directory '/root/linux/tools/testing/selftests'
make --no-builtin-rules ARCH=x86 -C ../../.. headers_install
make[1]: Entering directory '/root/linux'
INSTALL ./usr/include
make[1]: Leaving directory '/root/linux'
make[1]: Entering directory '/root/linux/tools/testing/selftests/vm'
make[1]: *** No rule to make target 'vm.c', needed by '/root/linux/tools/testing/selftests/vm/vm_64'. Stop.
make[1]: Leaving directory '/root/linux/tools/testing/selftests/vm'
make: *** [Makefile:175: all] Error 2
make: Leaving directory '/root/linux/tools/testing/selftests'

The TARGETS variable passed to tools/testing/selftests/Makefile collides
with the TARGETS used in tools/testing/selftests/vm/Makefile, so rename
the latter to VMTARGETS, eliminating the collision with no functional
change.
