libtool: update to 2.4.5; use xz

[ryandesign (Ryan Carsten Schmidt)]

proposed patch

[ryandesign (Ryan Carsten Schmidt)]

This will solve #46582.

[ryandesign (Ryan Carsten Schmidt)]

Using xz results in a smaller distfile download, and xz and its dependencies don't currently depend on libtool. However, it's possible one of them may at some point need to depend on libtool. For example, it was requested that gettext should depend on libtool in #38878. So maybe it is safer to stick with a distfile format that does not depend on another MacPorts port to be extracted. Perhaps a future version of MacPorts will be bundled with its own copy of the xz utils, as discussed recently on the mailing lists, and then it wouldn't be a problem.

I get this when I try to run libtoolize in this version. Anyone else seeing that?

Usually I’m all for using xz, but in this case I think we should stay on the safe side. It’s been all too easy in the past for someone (read: me) to accidentally introduce circular dependencies involving Autotools.

No, I haven’t encountered anything like that. Doesn’t seem like a Libtool problem. Ask on macports-users maybe?
