ok. linux-kselftest next has both shared logic and install patches
now. As I mentioned in my reply to shared logic patch, I had to drop
the changes to timers Makefile to add shared logic, hence timers progs
don't get installed at the moment.

Could you please review to make sure, it looks right.

As I said in the other email, if lib.mk could provide a way to run
additional programs that require arguments in addition to RUN_TESTS.
In the case of timers, there is one test that requires arguments. In
some cases, e.g: memory hotplug, override works well since it is just
one executable. In this case, there is a mix of executables that don't
need any special handling and some that need it.

You are welcome to add shared logic and install to timers if you would
like.

thanks,
