Subject: eal: fix build with gcc 9.0
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=3370975b994d793a89812031d86534916067dd67;hp=74f277101265ff3376c65270da2dcbc6d1325494;p=dpdk.git

eal: fix build with gcc 9.0

build error:
In function ‘eal_plugin_add’,
    .../lib/librte_eal/common/eal_common_options.c:225:2:
    error: ‘strncpy’ output may be truncated copying 4095 bytes from a
           string of length 4095 [-Werror=stringop-truncation]
    strncpy(solib->name, path, PATH_MAX-1);

strncpy may result a not null-terminated string,
replaced it with strlcpy
