    tools/libs: Fix build dependencies
    
    Some libs' Makefile aren't loading the dependencies files *.d2.
    
    We can load them from "libs.mk" as none of the Makefile here are
    changing $(DEPS) or $(DEPS_INCLUDE) so it is fine to move the
    "include" to "libs.mk".
    
    As a little improvement, don't load the dependencies files (and thus
    avoid regenerating the *.d2 files) during `make clean`.
