[svn-r11095] Purpose:
Configuration feature

Description:
Serial test output is now stored in log files and printed when all tests
in a directory complete, or when a test fails.  This should make test output
more readable and useful.
Also made changes to clean up ii_files directories that are created by some
C++ compilers/linkers.
Also fixed a few minor Makefile bugs.

Solution:
When serial tests run, their output is saved in *.log or *.logsh.  While
running, tests only print when they begin and when they complete; their
more specific output (from the log file) is printed if the test fails or
when all tests have completed.
Comments welcome.

Platforms tested:
mir, modi4 (parallel and serial), copper, shanti
