Ok, the `v1` content was `In order to build t2.c and t3.c; pass DPDK targets include and library path as compiler options.`. But as user adds other library functions are added to `examples/bpf' these may vary too.

Hence should we state as, `To build other BPF examples, appropriate libraries and dependencies is to be passed as command line options.`
