Fix broken compilation for non-numa aware platforms

- The dpdk plugin always looks for libnuma library during compilation.
   For non-numa aware platforms compilation breaks, if third party
   libnuma lib is not available.
 - Issue is more severe with Cross Compilation scenario where one has to
   download and cross compile libnuma-dev package even when target platofrom
   is NUMA disabled.
   Like when cross compiling for ARM platforms, Linaro tool-chain doesn't have
   libnuma by default.
