Have you built DPDK as a combined library?

Try adding the following option when building DPDK:

make install T=<rest of DPDK build command>  CONFIG_RTE_BUILD_COMBINE_LIBS=y

That's true for head of master (although DPDK 2.2 should work and there's a
pending patch to update docs/travis)

For OVS 2.4.0, INSTALL.DPDK.md says DPDK 2.0.0 is required. If you want
OVS 2.4.0 to work with a later build of DPDK then you'll need to backport
the OVS patches that were applied to master to enable this.
