[dpdk-dev] [PATCH 5/7] mk: Add hierarchy-file support (include)

[Mario Carrillo]

Add hierarchy-file support to the DPDK headers,
when invoking "make install H=1" (hierarchy-file)

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

headers will be installed in: $(DESTDIR)/usr/include
