It is hard for me to spot what exactly is missing, but while it was never
intended for trusty the version we have for xenial should get you going.
# all kind of dependencies
sudo apt-get install build-essential ubuntu-dev-tools debhelper dh-python
dh-systemd doxygen graphviz inkscape libcap-dev libpcap-dev libxen-dev
libxenstore3.0 python python-sphinx texlive-fonts-recommended
texlive-latex-extra
# get the version we currently package for xenial
pull-lp-source dpdk xenial
# run the packaged build which takes care of most enabling/disabling and
such
cd dpdk-2.2.0
./debian/rules build
Also as you need at least some SSE (level depends on your config) which
isn't in the guest by default.
Take a look at this - although I'm not 100% sure how mouch of it works back
on trusty.

Or just take the build process as your starting point for your own.
On the other hand I encourage you to go to 16.04 and just use the packaged
version if that would suit your needs.
