PATCH: PR libjava/32078: Update libtool in classpath

[H. J. Lu]

When libtool in gcc updated, libtool in classpath is out of sync
and classpath failed to build inside libjava. This patch copies
the new libtool from gcc toplevel with the modified libtool.m4:

With this patch plus a kludge:

I can build libjava on Linux/x86-64.
