    Update detection of find version in configure
    
    Commit 4028723 added code to detect the version of find
    because Debian is changing to a newer version of GNU
    find with different syntax than the traditional find.
    However, the change in that commit no longer worked on
    Mac OS X, a BSD-type system.
    
    Modify the find check to use the --version option supported
    on GNU and use GNU syntax if found. Otherwise default to the
    previous BSD syntax which was the previous setting for all
    systems.
