commit 1eff6db8f1dbf803c0b4a9fc1f601b1ac076bf8f
Author: Jens Hauke <hauke at par-tec.com>
Date:   Mon Aug 3 11:39:43 2015 -0500

    avoid dependency on GPFS if not requested
    
    Par-tec had an issue with libmpi.so depending on libgpfs even without
    romio configured to use it. Make the gpfs checks optional to remove
    the dependency.
