[spp] [PATCH] spp_pcap: fix inappropriate linking of liblz4

[ogawa.yasufumi@lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

In Makefile of spp_pcap, `liblz4.a` is linked directly as other source
codes. However, file path might be different on other distros, such as
CentOS or Fedora.

    SRCS-y += /usr/lib/x86_64-linux-gnu/liblz4.a

This update is to correct to link this library with `-l` option as
practical manner.
