I managed to get this taken care of before my weekend. You will see two
patches one with changes to lib.mk to add additional variables to avoid
overrides for cases like timers, and the other that updates timers to
use shared logic.

I did quick test running both make run_tests and make install to verify
timers programs are installed and run_tests works correctly.
