[svn-r14939] Purpose:      Bug Fix (Bug 794)

Description:  Test gcov script on kagiso

Solution:     The bin/gcov_script was not working on kagiso (it was written to
              be used on heping, but since we don't have heping anymore, we 
              need it on kagiso). There was a problem in that the generated
              .gcda files were being created in the /src/.libs directory when
              the script was expecting them to be in the /src directory. Also,
              -lgcov was added to LDFLAGS.

              The script performs configuration of HDF5 and runs the tests, and
              generates code coverage statistics for the source code files,
              which it places in the gcov_logs directory.

              The individual *.gcov files show the number of times each 
              individual line of the associated source file is executed, and
              displays branches tken information as well. The file gcov.log
              shows a summary of each source file's coverage statistics in one
              easily accessible file.

Tested:       kagiso
