[dpdk-dev] [PATCH] mk: fix dependencies to optional configs

[Olivier Matz]

In rte.lib.mk, the list of libraries passed to the link
command (LDLIBS) is generated from the DEPDIRS-xxx variables.
If a library is not compiled because it is disabled in
configuration, it should not appear in DEPDIRS-xxx.

- librte_port depends on librte_kni only if it is enabled.
- librte_table depends on librte_acl only if it is enabled.
