Subject: mk: forbid multiple definitions
X-Git-Tag: spdx-start~9913
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a32e8b0db67c9954d01349e458649994f432ffae;p=dpdk.git

mk: forbid multiple definitions

The option "-z muldefs" was set only if not using ld directly.
By the way, this option seems to be a useless hack introduced
with shared and combined libraries support (e25e4d7ef16b8aa84de).
The clean approach is to remove it.
