hdf5_ep

[svn-r6996] Purpose:
bug fix and cleanup

Description:
Previous change messed things up that fortranlib_test was linked
with multiple MAIN because $(TEST_OBJ) was used as if it was for
fortranlib_test only.


Solution:
Created a separated $(FORTLIBTEST_OBJ) for the fortranlib_test test.
Adjusted other related symbol names.

Also, removed DISTCLEAN=* which held files that should have been
removed in MOSTLYCLEAN.

Platforms tested:
"h5committested" (modi4, sol, verbena).
In the process of running fortran tests in arabica and kelgia.

Misc. update:
