In the Cygnus tree we use a short patch to libtool instead. This
works everywhere that libtool works.
I don't like the idea that I have to remember if a directory uses
libtool in order to figure out the target name. I guess we could add
new targets to handle that though:
(People here do use these targets regularly.)

But it is a bug that will have to be fixed someday, right? libgcj
will eventually be ported.

I'm glad that Jeff put in the patches to do this, but I don't think
this is a supported mode. It isn't something we advertise on the
libgcj web page, for instance.
