    Remove a bitrotted hack for OpenBSD and NetBSD regarding the dyn way.
    
    On OpenBSD and NetBSD, we were accidentally passing "-optl-pthread" to
    the gcc to build dynamic libraries because of a bitrotted hack for
    those OSes, which resulted in a weird situation where every dynamic
    library is named "ptl-pthread" and placed at "$(TOP)".
    
    The hack in question were to work around a linkage problem with
    libHSffi, but we no longer build it and just use libffi these days so
    the hack can safely be removed.
