  In what way are these DLLs "shared"?  They are target libraries, they aren't
linked into the cross-compiler itself, and applications built by the
cross-compiler don't link directly against the DLLs anyway, they have import libs.

  I think it would be cleaner if the right -bindir settings were sent to
libtool during the build/install process.  This is PR40125(*), btw.  Which I'm
down to fix, I guess I'd better get on with it.

    cheers,
