Commit Message

Documentation/dev-tools/kselftest.rst says you can use the "TARGETS"
variable on the make command line to run only tests targeted for a
single subsystem:

  $ make TARGETS="size timers" kselftest

A natural way to narrow down further to a particular test in a subsystem
is to specify e.g., TEST_GEN_PROGS:

  $ make TARGETS=net TEST_PROGS= TEST_GEN_PROGS=tun kselftest

However, this does not work well because the following statement in
tools/testing/selftests/lib.mk gets ignored:

  TEST_GEN_PROGS := $(patsubst %,$(OUTPUT)/%,$(TEST_GEN_PROGS))

Add the override directive to make it and similar ones will be effective
even when TEST_GEN_PROGS and similar variables are specified in the
command line.
