[ovs-dev] [PATCH] acinclude: check for numa library

[Bhanuprakash Bodireddy]

Numa library is needed for NUMA aware vHost User functionality.
Incase of missing numa package, the OVS DPDK configuration fails with
"error: Could not find DPDK libraries in <DPDK_LOC>/TARGET/lib" though
the DPDK library is installed.

This patch fixes this inappropriate error by checking for presence of
numa library and output an appropriate error message "error: unable to 
find libnuma, install the dependency package" in case of missing package.
