[svn-r2572] Purpose:
    Feature
Description:
    Most tests are done inside a for-loop.  Whenever a test exits
    with error, the for-loop does a "exit 1" to exit the make.
    "make -i" could not catch and ignore the error status.
Solution:
    Replaced "exit 1" with break.  At the end of the for-loop,
    test if all tests have been run.  If not, the for-loop is
    ended by the break command, thus raise an error.  Now,
    'make -i' can catch and ignor it.
    Also added the test of variable HDF5_Make_Ignore inside the
    for-loop to indicate the desire to ignore errors when the
    HDF5_Make_Ignore is set to a non-null/blank string.
Platforms:
    Tested on modi4 and eirene.
