Log Message:
make: document the history of bugs in "cmdline overrides global"

For performance reasons, the implementation of the simple rule "cmdline
overrides global" grew into code that is much more complicated than a
straight-forward implementation.  This added complexity made it easy for
bugs to sneak in.
