No.  I'm not using the installed libtool.  I'm building it as part of
the cross-development environment.  Now, I know that I have to build
two version: one for native packages and one for cross-compiled
packages.

I don't think that's the problem.  What's happenng is libtool is
pulling host's standard libraries (e.g. libstdc++) instead of the
cross-compiler versions.  So, I considered doing as you suggest, but
it seems like a nasty hack, especially because I don't have any way of
knowing which libraries it's going to try to pull.  Building a cross
targeted libtool means that the packages that use it don't have to be
aware of this problem..

Cheers.
