[dpdk-dev] [PATCH] librte_vhost: eventfd_link: Update the makefile to build against an arbitrary kernel

The vHost eventlink driver is a kernel module that requires a kernel
source/build directory to build the ko. Convert the fixed kernel build
directory specifier to one which may be user specified on the command-line.
