[dpdk-dev] [PATCH v7 01/11] mk: Add rule for installing headers

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

Add hierarchy-file support to the DPDK headers,
when invoking "make install-headers" headers will
be installed in: $(DESTDIR)/$(includedir)
where includedir=$(prefix)/include/dpdk and prefix=/usr/local by
default, you can override "prefix" and "includedir" vars.
This hierarchy is based on:
http://www.freedesktop.org/software/systemd/man/file-hierarchy.html
and variables are based on:
https://www.gnu.org/prep/standards/html_node/Directory-Variables.html
https://www.gnu.org/prep/standards/html_node/DESTDIR.html
