[dpdk-dev] [PATCH 1/7] mk: Add hierarchy-file support

[Mario Carrillo <mario.alfredo.c.arevalo@intel.com>]

Add hierarchy-file support to the DPDK scripts, tools, examples,
makefiles and config files when invoking "make install H=1"
(hierarchy-file)

This hierarchy is based on:
http://www.freedesktop.org/software/systemd/man/file-hierarchy.html
and dpdk spec file.

scripts, tools, examples, makefiles and config files will be installed
in: $(DESTDIR)/usr/share/dpdk
