[svn-r6764] Purpose:
Improvment

Description:
No default setting of fortran compiler when --enable-parallel is
used.

Solution:
Changed it to use mpxlf_r as the default parallel fortran compiler.
This is consistent with the default C compilers.

Platforms tested:
Did not h5committested because the changes were made offsite.
Tested in LLNL SP BLUE, both serial and parallel modes.
(There is a compiling error in src but the configure result are
verified.)

Misc. update:
    Update MANIFEST if you add or remove any file.
    Update release_docs/RELEASE for bug fixes, new features, etc.
    Update applicable document files too.
