Remove ports README and update machine ChangeLogs.

This patch removes the ports/README now that ports is no longer
being used. It also adds a header to all ChangeLogs for all machines
that were moved to the main libc tree. The header indicates that the
ChangeLog is no longer used.
Final update to ports ChangeLog.

Indicate the removal of the README and carry out the
final update to the ports/ChangeLog.
