[PATCH] D18086: Fix default processor name for armv6k.

I seem to have a related issue: I am using -march=armv6k and -no-integrated-as, this generates the following output:

  	.text
  	.syntax unified
  	.eabi_attribute	67, "2.09"	@ Tag_conformance
  	.cpu	arm1176jz-s
  	.eabi_attribute	6, 6	@ Tag_CPU_arch
  	.eabi_attribute	8, 1	@ Tag_ARM_ISA_use
  	.eabi_attribute	9, 1	@ Tag_THUMB_ISA_use
  	.fpu	vfpv2
  	...

With that the GNU assembler subsequently errors out:

  /tmp/empty-bc2ea3.s: Assembler messages:
  /tmp/empty-bc2ea3.s:4: Error: unknown cpu `arm1176j-s'

According to the binutils documentation <https://sourceware.org/binutils/docs-2.24/as/ARM-Options.html> arm1176j-s is not a valid CPU. Using -mtune=arm1136jz-s does not help. But armv6kz seems to work (uses cpu arm1176jzf-s).
