selftests/bpf: do not ignore clang failures
When compiling an eBPF prog fails, make still returns 0, because failing clang command's output is piped to llc and therefore its exit status is ignored. When clang fails, pipe the string "clang failed" to llc. This will make llc fail with an informative error message. This solution was chosen over using pipefail, having separate targets or getting rid of llc invocation due to its simplicity. In addition, pull Kbuild.include in order to get .DELETE_ON_ERROR target, which would cause partial .o files to be removed. Signed-off-by:Ilya Leoshkevich <iii@linux.ibm.com> Acked-by:
