PATCH: should use AC_PROG_LIBTOOL in opcode.

[Masaki Muranaka]

Hello,

There is used AM_PROG_LIBTOOL in opcode/configure.in.
AM_PROG_LIBTOOL is already obsolete and autoreconf seems be confused.
It shows a message like this:
 > autoreconf: configure.in: not using Libtool

And it seems AM_PROG_LIBTOOL causes some troubles using with  
libtools-2.2 .
(I've not figure out why it caused yet.)
