mk: optimize directory dependencies Before this patch, the management of dependencies between directories had several issues: - the generation of .depdirs, done at configuration is slow: it can take more than one minute on some slow targets (usually ~10s on a standard PC without -j). - for instance, it is possible to express a dependency like: - app/foo depends on lib/librte_foo - and lib/librte_foo depends on app/bar But this won't work because the directories are traversed with a depth-first algorithm, so we have to choose between doing 'app' before or after 'lib'. - the script depdirs-rule.sh is too complex. - we cannot use "make -d" for debug, because the output of make is used for the generation of .depdirs. This patch moves the DEPDIRS-* variables in the upper Makefile, making the dependencies much easier to calculate. A DEPDIRS variable is still used to process library dependencies in LDLIBS. After this commit, "make config" is almost immediate.

mk: do not generate LDLIBS from directory dependencies The list of libraries in LDLIBS was generated from the DEPDIRS-xyz variable. This is valid when the subdirectory name match the library name, but it's not always the case, especially for PMDs. The patches removes this feature and explicitly adds the proper libraries in LDLIBS. Some DEPDIRS-xyz variables become useless, remove them.
