Fixed bug #591

 Wade Berrier      2008-05-28 11:09:42 PDT

configure.in will enable dynamic loading by default for modules, but some of
the checks only check /lib, /usr/lib, /usr/local/lib, etc...

It needs to also account for systems using /lib64, /usr/lib64, and
/usr/local/lib64.

For example, openSUSE x86_64 distro uses these style paths.  Otherwise, i586
gets dynamically loaded, but x86_64 doesn't.
