gcc defaults to silence (off) for the following warnings, but clang defaults to the opposite. These warnings are not useful for kselftests, so silence them for the clang builds as well:
-Wno-address-of-packed-member -Wno-gnu-variable-sized-type-not-at-end
This eliminates warnings for the net/ and user_events/ kselftest subsystems, in these files:
./net/af_unix/scm_rights.c ./net/timestamping.c ./net/ipsec.c ./user_events/perf_test.c
