Message:

binutils-pass2: Reword the paragraph about libtool workaround

Well, I was blaming libtool too much. If the entire Binutils tree uses
libtool this won't happen. The problem is Binutils building system is
using libtool-style idiom on non-libtool components.

And this issue is not related to cross compiling, at all. A native
build can exploit the issue as well (see the updated comment).

Maybe I'll submit a patch to GCC (yes, not a typo, GCC is the upstream
of Binutils building system) to fix the issue when I have the mood...
