[svn-r6739] Purpose:

    Bug Fix

Description:
    H5FC was failing on Copper (IBM P690). The reason: the xlf compiler
    needs files to end in .f in stead of .f90. If you have .f90 files,
    you need the "-qsuffix=f=f90" flag defined. This was defined for
    compiling things via the "-c" option (to object files) but not for
    straight compilation of a file.

    I also noticed that the directory modules were being extracted from
    was "." and "../src". H5FC would find these alright when doing a
    "make check-install" but if Suzie User were to try this, it might
    fail for her. Suzie would have to specify explicitly where to grab
    these files.

Solution:
    The solution to the problem was a bit more involved. I added a new
    variable called "F9XSUFFIXFLAG" which is set to this value if the
    machine needs it.

    Added new variable called "FSEARCH_DIRS" which can be set to the
    directories to find modules during compilation. The H5FC script knows
    where to find the correct modules (it's in the lib/ directory), so it
    uses the F9XMODFLAG to find them and not the FSEARCH_DIRS flag.

Platforms tested:
    Modi4 (Fortran & Parallel)
    Verbena (Fortran) C++ not needed since this is Fortran-only fix
    Arabica (Fortran)
    Copper (Fortran)

    Ran "make install" and "make check-install" afterwards...
