[svn-r11431] Purpose:
New feature.

Description:
Added the time command to the make check target to report time usage
of the execute of each test and test scripts.  This gives us some idea
how long each test takes and some vague idea it is compute bound or
not.

powerpc-ibm-aix5.x:
Change $RUNPARALLEL default setting to allow it being invoked by the
time command.

Platforms tested:
h5committested.
