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: 27cea11686ff ("net/mlx4: spawn rdma-core dependency plug-in")
Fixes: 59b91bec12c6 ("net/mlx5: spawn rdma-core dependency plug-in")
