Subject: examples: fix pkg-config override
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=11e027022d0f72f3cd7419b83e69a9ceb342666d;p=dpdk.git

examples: fix pkg-config override

Move pkg-config override to beginning in the Makefile to allow
use PKGCONF variable to detect the libdpdk availability.

Fixes: fda34680eb9a ("examples: remove legacy sections of makefiles")
Cc: stable@dpdk.org
