        src/usr.bin/make: dir.c

Log Message:
make(1): initialize global variables in dir.c

Calling CachedDir_Assign requires that the variable be initialized.  On
most systems, NULL is represented as all-zero bits already.  This change
is only for the few other systems.

Add some comments explaining the implementation of Dir_AddDir since that
is tricky to read from the code alone.
