From: Mohamad Noor Alim Hussin <[email protected]> The generated pkg-config libdpdk.pc file has the output with full path of librt such as <builddir>/recipe-sysroot/usr/lib/librt.so instead of -lrt.
This will cause an issue when compile DPDK app with static library as the librt is not found with the hardcode path in the libdpdk.pc file.
