[Buildroot] [PATCH] sh64: drop support for architecture

[Waldemar Brodkorb <wbx@openadk.org>]

There seems to be no hardware or emulator available for this
architecture. Someone from ST Microelectronics told me that
sh64/sh5 projects are dropped over ten years ago.
I found nothing about real hardware on the sites of Hitachi
or Renesas.
We should drop this.
Support in uClibc-ng will be dropped in 1.1.

Signed-off-by: Waldemar Brodkorb <wbx@openadk.org>

Or does anyone know of any sh64/sh5 hardware?
