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.
