I'm not sure upgrading to the "latest" libtool will actually fix
much.  I see no evidence that it fixes the .la problem (searching
/lib instead of /lib64).

The main problem with upgrading libtool is that it will require
upgrade configure.in (and openldap.m4) to latest autoconf.  That's
a major chore.

I just had to do two things:

To get it to link the shared libraries correctly:
        s%-shared%-m64 -shared%

To get it to ignore .la files in {/usr,}/lib (when linking slapd):
        s%/lib%/lib64%

I can easily fix libtool to do this when -m64 is specified.
