When linking the mlx glue code libraries using CC, the linker arguments in LDFLAGS are not prefixed with -Wl. [The EXTRA_LDFLAGS are though.] This leads to warning messages on build: clang-5.0: warning: argument unused during compilation: '-e xport-dynamic' Fix this by checking for $LINK_USING_CC in the Makefiles and prefixing the LDFLAGS appropriately if set. Fixes:27cea11686("net/mlx4: spawn rdma-core dependency plug-in") Fixes:59b91bec12("net/mlx5: spawn rdma-core dependency plug-in") Cc: stable@dpdk.org Signed-off-by: Bruce Richardson <bruce.richardson@intel.com> Acked-by: Yongseok Koh <yskoh@mellanox.com>
