I have rebased the code a few times, so I may have missed some info :)
I did try to update DEPDIRS with required info but it was all manual work.
As you menion, LDLIBS and DEPDIRS are mostly similar but in DEPDIRS we
also specify dirs
that would install required headers such as ether, mempool and mbuf.
By the way, I just realized that -lethdev is not required. It is not an
issue because we link
with --as-needed so only required libs would have DT_NEEDED entries (if
you do ldd on the
shared library you would not see a dependency for ethdev).
I could have added eal too as DEPDIRS, but it is already implicit by
having mempool and malloc.

I did add '-z defs' to LDLIBS (except for eal) so the linker would
complain if any of the
symbols was not resolve at build time. With this flag we can check that
all the required libs
are specified. If we specify libs that are not required, the linker
would ignored them anyway.
So initially I set LDLIBS to the values of DEPDIRS, then checked that if
some libraries were still
required, finally updating proper LDLIBS. To answer your question, I
guess all was manual work.
My first patch did add this flag by default when linking libs but I
removed as we decided
to leave eal without proper DT_NEEDED entries.

I'll be sending a v2 with corrected commit for the last patch and I'll
remove -lether from
librte_ip_frag.
Let me know if you have any other comments/suggestions.
Thanks for the review!
