[svn-r6886] Purpose:

    Update

Description:
    GPFS should only be checked for if the --enable-gpfs flag is used.
    Otherwise, it shouldn't.

Platforms tested:
    Linux (Configure only fix so only needed to test it to make sure the
           configure does the right thing and that the build won't
           break. I need to test it on a machine that has GPFS to make
           sure it works there...)
