re-do how gdbarch provides non-multi arch defaults so that non-

multi-arch gdbservers can continue to compile.

+       * gdbarch.sh: Provide non- multi-arch defaults by direct
+       definition in "gdbarch.h" instead of going through "gdbarch.c".
+       * gdbarch.h, gdbarch.c: Re-generate.
+       * defs.h: When non- multi-arch, include "arch-utils.h" so that
+       legacy definitions are globally visible.
+
