libtool request

[Andres Salomon]

Hi,

Would it be possible to update the libtool used when building the
release tarballs to something newer than 1.4.3?  1.4.3 is pretty old
(released 2002-10-22); the 1.5.x releases contain many improvements,
some that distributions (ie, Debian) need for their ports.  Updating
this should be as easy as simply upgrading libtool on the system that is
used when running the bootstrap script.
