[Buildroot] [PATCH] kexec: disable on unsupported architectures

[spdawson at gmail.com <spdawson@gmail.com>]

From: Simon Dawson <spdawson@gmail.com>

kexec only supports the following architectures.

  i?86
  powerpc
  powerpc64
  arm*
  s390x|s390
  sh4|sh4a|sh3|sh
  mips*
  cris
  crisv32
  ia64
  x86_64
  alpha

The Buildroot kexec package is available when an unsupported target
architecture is selected, leading to autobuild failures like the following.

  http://autobuild.buildroot.net/results/e706b08abb4fd1987fc4aa970d6be50fc92dc1fa/build-end.log

This patch makes the kexec package available only for the supported
architectures.
