amd64/ppc64 patch for admin/libtool.m4.in

[Ben Burton]

Hi,

The debian amd64 people have offered the following patch for
admin/libtool.m4.in.  The situation is that, on debian amd64 systems,
/lib64 is a symlink to /lib and so the "64" suffix should not be used.

The patch below simply adds a test for whether /lib64 is a symlink.  For
other distributions where /lib64 is a real directory, nothing should
change.

Would you be happy to include this patch in admin/ ?  The patch is
against KDE_3_3_BRANCH, but both KDE_3_4_BRANCH and HEAD have the same
issue.

I'm CCing Andreas Jochens who supplied the patch (since I don't actually
have a 64-bit system at all, and I can't offer much insight into amd64
issues).  Please CC him with any replies.

Andreas: Please note that this single admin/ directory gets propagated
to all KDE modules, so this should address several of the bug reports
that you've filed.

Thanks - Ben.
