[PATCH 0/8] Fix clean target warnings

[Shuah Khan]

This patch series consists of changes to lib.mk to allow overriding
common clean target from Makefiles. This fixes warnings when clean
overriding and ignoring warnings. Also fixes splice clean target
removing a script that runs the test from its clean target.

[PATCH 2/8] selftests: lib.mk: define CLEAN macro to allow Makefiles to override clean

[Shuah Khan]

Define CLEAN macro to allow Makefiles to override common clean target
in lib.mk. This will help fix the following failures:

warning: overriding recipe for target 'clean'
../lib.mk:55: warning: ignoring old recipe for target 'clean'

Should probably have:

Fixes: 88baa78d1f31 ("selftests: remove duplicated all and clean target")


In hindsight I'm not sure moving the clean target into lib.mk was
the best idea, but anyway it's a bit late to change our mind on that.

This patch is a good solution to fix the warnings.

Amended the change log to add the above.

Yeah. Moving clean target to lib.mk ended up to be problematic. However,
there are some advantages as well. It will simplify some Makefiles. One
thing that was missed was that not finding the Makefiles that require
overrides. Anyway live and learn.

Thanks. I plan to apply the patch with the amended changelog and your
Ack. Please let me know if you want to see v2 with the change sent out.

If might be easier to do something like:

ifneq($(NO_CLEAN),y)
clean:
	$(RM) -r $(TEST_GEN_PROGS) $(TEST_GEN_PROGS_EXTENDED) $(TEST_GEN_FILES) $(EXTRA_CLEAN)

I am not sure that it is easier. Defining a macro would work well
in this case to override and also works well with what we are doing
for other overrides we already have such as EMIT_TESTS.

gpio clean requires special handling. I have one more patch
I sent out that handles that. So I am going to leave this
patch the way with override.

Simpler as:

EXTRA_CLEAN := $(BINARIES_32) $(BINARIES_64)

Actually for builds that insist on crapping all over the source tree I've used:

clean:
	rm -rf `cat .cvsignore 2>/dev/null`

Applied with amended change log and Michael's ack to linux-kselftest next

Applied all of the above to linux-kseltftest next

Applied v2s addressing Michael's comments to linux-kselftest next
x86 fix also addresses not being able to build ldt_gdt

make -C tools/testing/selftests/x86 ldt_gdt
