[OE-core] [RFC][PATCH] arch-armv4.inc: add --fix-v4bx to TARGET_LD_KERNEL_ARCH only for armv4 and strongarm1100

[Martin Jansa]

* without this patch it does apply --fix-v4bx not only to armv4, but
  also all higher (because they also have armv4 in TUNE_FEATURES)
* it causes SIGILL on armv4t
  http://lists.linuxtogo.org/pipermail/openembedded-devel/2012-November/042298.html
* someone please test on armv4 device (I tested only bitbake -e output
  that it's correctly applied with DEFAULTTUNE == armv4
* maybe we can should fix this in binutils instead (both 2.22 and 2.23
  are affected)
