build: remove DPDK_DIR

Browse Source 
This is an artifact from before SPDK had a configure
script or a DPDK submodule.  Make configure the
only supported way for specifying the location of the
DPDK installation to use with SPDK.

@ -50,6 +50,14 @@ Default config file pathnames have been removed from iscsi_tgt, nvmf_tgt
and vhost. Config file pathnames may now only be specified using the
-c command line option.
Users may no longer set DPDK_DIR in their environment to specify the
location of the DPDK installation used to build SPDK. Using DPDK_DIR
has not been the documented nor recommended way to specify the DPDK
location for several releases, but removing it ensures no unexpected
surprises for users who may have DPDK_DIR defined for other reasons.
Users should just use the "configure" script to specify the DPDK
location before building SPDK.
