Before we were unshare(CLONE_NEWCGROUP)ing in a child task, which meant
that we couldn't c/r this test once we forbid nested cgroup namespaces.
Instead, use a new strategy for testing cgroup namespaces: set up the
namespace before forking the test task so there is no nesting, and then do
a setns back to init's ns to check the cgroup namespace of the test. This
doesn't work in the 'ns' flavor because init in the test's pid ns is the
test itself. There is a bit of a chicken and egg problem here, though,
because if we set it up after test_init(), we can't unshare because that
would be a nested cgroup ns.

With GNU make, using .PHONY leads to the same result as using
the "FORCE" hack, but unlike FORCE is not a hack. Since we do not
plan to use any other make than GNU make, let's just mark phony
targets as such.
For more details about why PHONY is better than FORCE, see

Move static and transition into zdtm top. We can't move all the micro

Because of the #undef (probably left over from some debugging I did that
accidentally got committed), this test never ran. Anyway, this is all

The issue here is that ARCH is not overwritten if the caller Makefile
already define it, and the upper Makefile is not overwriting the ARCH
define to "arm", when it is "armv7l" for instance, so the SRCARCH is
set to "armv7l" which is wrong.
With this patch, SRCARCH is using the inherinted define if called from
the top level Makefile.
This is required to build test on armv7l architecture (qemu).
