35### To add a new directory to the tree, first choose whether it is a target
36### or a host dependent tool. Then put it into the appropriate list
37### (library or tools, host or target), doing a dependency sort. For
38### example, gdb requires that byacc (or bison) be built first, so it is in
39### the ${host_tools} list after byacc and bison.
