* solib.c (solib_add): New argument is the target_ops whose

        section list is to be added to, if any.  Reallocate the
        sections in that target to add any that come from shared libs.
        (throughout) so_sections renamed to sections.
        (solib_xfer_memory):  Deleted.
        * tm-sunos.h (SOLIB_ADD):  Add target argument.
        (SOLIB_XFER_MEMORY):  Delete.

        * xm-sun3os4.h, xm-sun4os4.h:  Define BROKEN_LARGE_ALLOCA,
        and add comment explaining shared library screw.
