Description: Fix the build file and directory dependencies.
 Create a build/created.stamp file and depend on it instead of
 the build/ directory itself when checking for stale object and
 executable files. This fixes a problem with make(1) considering
 everything as out of date since the build/ directory's timestamp
 has been updated after the object files within it.
