[svn-r3516] Purpose:
    New feature
Description:
    Added a -debug line option and will pass it to other runtest invoked.
    Removed the restriction of running one test per host.  This way,
    tests of different tests (e.g., with or without fortran) can be
    run per host with all output saved in one log file.
Platforms tested:
    Tried several runs of daily test.
