Re: Fix libjava x86-64 multilib


The libtool maintainers have accepted the libtool patch, I'll add it
here again for reference.

What's the right way to add it?  Shall I just add this hunk and commit
it - and then run autoconf on java/configure and commit the new
configure also?  Or what needs to be done with incorporating this
change?
