[dpdk-dev] DPDK PDUMP Issue

[Varghese, Vipin]

Hi Dikshant,

Looks like the custom Makefile log is quite different in passing DPDK CFLAGS and LDFLAGS. Also here are couple of surprises for me 

1. Unable to find `make -n` logs

2. presence of g++ is present in each line

3. unable to find include option

4. request was to run `make -n` and cross the relevant libraries are bound within the `-Wl,--whole-archive` and `-Wl,--no-whole-archive `. 

5. Unable to find `-Wl,-lpcap` passed for `-Wl,-lrte_pmd_pcap -Wl,-lrte_pdump`

Hint: I normally take up sample like example/l2fwd and work towards to removing unwanted libraries while keeping the content and format intact for my custom makefile.
