[PATCH v6 01/10] 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: $(DESTDIR)/$(INCLUDE_DIR)
where INCLUDE_DIR=$(RTE_PREFIX)/include/dpdk and RTE_PREFIX=/usr/local
by default, you can override RTE_PREFIX and INCLUDE_DIR vars.
This hierarchy is based on:
http://www.freedesktop.org/software/systemd/man/file-hierarchy.html
