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.
