Public bug reported:

See:
ldd usr/lib/x86_64-linux-gnu/libdpdk.so.0                                                                                                                                               
        linux-vdso.so.1 =>  (0x00007ffc977e3000)                                                                                                                                             
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fb7594da000)                                                                                                                    
        /lib64/ld-linux-x86-64.so.2 (0x0000557d9e648000)

While a consume of libdpdk can fix that op on his own by providing the
right -l parameters it will fail with errors like this if he doesn't

So eventually the library libdpdk.so.0 should link itself against the libraries it uses.
