[dpdk-dev] [PATCH v2 4/8] mk: Add rule for installing modules

[Mario Carrillo]

Add hierarchy-file support to the DPDK modules,
when invoking "make install-mod" for this case
if RTE_EXEC_ENV=linuxapp modules will be installed
in: $(DESTDIR)/lib/modules/$(uname -r)/build else they will be in:
$(DESTDIR)/boot/modules
This hierarchy is based on:
http://www.freedesktop.org/software/systemd/man/file-hierarchy.html
