Usually, if you only want to make a sub group of tests. Then you cd into
the sub directory and do 'make'.

So why do we need three targets?

Just an idea, but maybe in a future patch this could run some actual
tests as well? A lot of the old syscall tests would be fine to run in
CI. More likely if they fail it is due to LTP library changes than a
kernel bug on the host.
