[svn-r11330] Purpose:
Bug fix

Description:
Errors on sol may have been due to "make clean" being run both
manually and by automake.  Removed the manual run.
Also cleaned c++/examples/ii_files directory created by some compilers
(e.g., on modi4).

Solution:
This does mean that examples directories will not be cleaned by
'make clean'.

Platforms tested:
sol, mir, heping, modi4
