[dpdk-dev] [PATCH] net/mlx5: fix linkage error for glue lib

[Shahaf Shuler <shahafs@mellanox.com>]

From: Yaroslav Brustinov <ybrustin@cisco.com>

Compiling with gcc 4.7.2 introduced the linkage error

"bin/ld: Warning: alignment 8 of symbol `mlx5_glue' in
src/dpdk/drivers/net/mlx5/mlx5_glue.c.21.o is smaller than 16 in
src/dpdk/drivers/net/mlx5/mlx5_rxq.c.21.o"

Fix it be forcing the alignment of the glue lib.

Fixes: 0e83b8e536c1 ("net/mlx5: move rdma-core calls to separate file")
