[dpdk-dev] [PATCH v9 05/11] mk: Add rule for installing documentation

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

Add hierarchy-file support to the DPDK documentation,
when invoking "make install-doc" documentation files will
be installed in: $(DESTDIR)/$(docdir) where
docdir=$(datarootdir)/doc/dpdk
datarootdir=$(prefix)/share
prefix=/usr/local by default, you can override "prefix",
"datarootdir" and "docdir" vars.
also if "make doc" was invoked previously, html and pdf documentation
will be included in this path
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
