Subject[PATCH 07/12] selftests: memfd: Fix build with O=
Date
When building kselftest in a separate output directory:

make[3]: *** No rule to make target 'common.o', needed by '/tmp/kselftest/memfd/memfd_test'. Stop.

Fix this by explicitly listing common.o (in the output tree) in the
build targets (allowing the EXTRA_CLEAN rule to be dropped), and
updating the dependencies of the final executables.
