[dpdk-dev] [PATCH 3/3] mk: allow to specify DESTDIR in build rule

[Thomas Monjalon <thomas.monjalon@6wind.com>]

From: Olivier Matz <olivier.matz@6wind.com>

This will install the binary sdk (bin + modules + libs + headers + mk)
in the specified directory.
This directory can be used as RTE_SDK by external applications.
