All directory targets now install the Makefile only if it is missing.

Browse Source 
Directory targets no longer check for existance of the directory in the
object tree; if the Makefile doesn't exist, we will re-create the directory.
This seems to be a pretty good assumption and saves us from checking
directory existance each time.
