Latest shared-lib makefile revisions fail on HPUX

Somebody didn't take into account the possibility that $(shlib)
is the same name as lib$(NAME)$(DLSUFFIX).

install-shlib: $(shlib)
    $(INSTALL) $(INSTL_SHLIB_OPTS) $(shlib) $(LIBDIR)/$(shlib)
    rm -f $(LIBDIR)/lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION)
    rm -f $(LIBDIR)/lib$(NAME)$(DLSUFFIX)
    cd $(LIBDIR) && $(LN_S) -f $(shlib) lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION)
    cd $(LIBDIR) && $(LN_S) -f $(shlib) lib$(NAME)$(DLSUFFIX)

This deletes the actual shared lib and replaces it with a symlink
pointing to itself.   Grumble.  The debris:

BTW, the install for plpgsql.sl is not right either --- it doesn't have
this symlink problem, but the permissions on the file are wrong.  HPUX
wants shlibs to be executable.
