You mean ltmain.sh, right?

It'd be nice to know
- the exact libtool version used
- a small test case to reproduce the behavior (esp. Makefile.am snippet)
- which of the details above trigger the behavior
  (does the fact that you are cross-compiling do this?)
- a `--debug' output of the `--mode=link' step of the library
- `$(TOP)/scripts/config.guess`
- contents of autogen.sh if that does fancy stuff other than a
  autoreconf.

I need to remark that cross-compile support in Libtool is suboptimal
ATM.  We want to change that, but it will take quite a bit of work.
