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

[Mario Carrillo]

Add hierarchy-file support to the DPDK modules for linux,
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)/lib/modules
