selftests/bpf: fix broken build, take 2
Merge of 'linux-kselftest-4.11-rc1': 1. Partially removed use of 'test_objs' target, breaking force rebuild of BPFOBJ, introduced in commit d498f8719a09 ("bpf: Rebuild bpf.o for any dependency update"). Update target so dependency on BPFOBJ is restored. 2. Introduced commit 2047f1d8ba28 ("selftests: Fix the .c linking rule") which fixes order of LDLIBS. Commit d02d8986a768 ("bpf: Always test unprivileged programs") added libcap dependency into CFLAGS. Use LDLIBS instead to fix linking of test_verifier. 3. Introduced commit d83c3ba0b926 ("selftests: Fix selftests build to just build, not run tests"). Reordering the Makefile allows us to remove the 'all' target. Tested both: selftests/bpf$ make and selftests$ make TARGETS=bpf on Ubuntu 16.04.2.
