1.0.28.1: disable address space randomization on Linux/x86-64

 * At least some Red Hat versions do randomization on x86-64 as well,
   whereas we used to assume only x86 had this "feature".

+  * bug fix: disable address space randomization Linux/x86-64 as well,
+    not just x86-64. (reported by Ken Olum)
+
 changes in sbcl-1.0.28 relative to 1.0.27:
   * a number of bugs in cross-compilation have been fixed, with the ultimate
     result that building under (at least) clisp should be much more reliable.
