Subject: [svn-r6883] Purpose:     Bug Fix

Description:
    Lots of things. Mostly, multiple libraries declared on the command
    line bothered some compilers. Then the order of the libraries is
    important. Then if you are building static, you don't want an
    "-lhdf5" flag in your compile line.

Solution:
    Various hacks to remove redundant libraries from the compile line and
    to keep the order of them and to replace -lhdf5 with the .a file when
    building static.

Platforms tested:
    Modi4 (Fortran & Parallel)
    Verbena (Fortran & C++)
    Arabica (Fortran)
