[svn-r9969] Purpose:

Correction to previous print_manager_output bugfix

Description:
Although the previous bugfix did fix all the errors, it was not the correct way
to fix the problem.  Since the manager will only buffer output when run in
parallel mode, in serial mode this function should not even be called.

Solution:
Wrapped print_manager_output in #define's to prevent it from being included in
serial builds.


Platforms tested:
heping (serial + parallel)
