kselftest: add capability to skip chosen TARGETS

Let the user specify an optional TARGETS skiplist through the new optional
SKIP_TARGETS Makefile variable.

It is easier to skip at will using a reduced and well defined list of
possibly problematic targets with SKIP_TARGETS than to provide a partially
stripped down list of good targets using the usual TARGETS variable.

@ -89,6 +89,22 @@ To build, save output files in a separate directory with KBUILD_OUTPUT ::
$ export KBUILD_OUTPUT=/tmp/kselftest; make TARGETS="size timers" kselftest
Additionally you can use the "SKIP_TARGETS" variable on the make command
line to specify one or more targets to exclude from the TARGETS list.
To run all tests but a single subsystem::
$ make -C tools/testing/selftests SKIP_TARGETS=ptrace run_tests
You can specify multiple tests to skip::
$ make SKIP_TARGETS="size timers" kselftest
You can also specify a restricted list of tests to run together with a
dedicated skiplist::
$ make TARGETS="bpf breakpoints size timers" SKIP_TARGETS=bpf kselftest
See the top-level tools/testing/selftests/Makefile for the list of all
possible targets.
