[PATCH next] ARM: virt: fix build of hyp-stub

Compile hyp-stub explicitly for arm v7-a. This fixes the following build
errors:

  arch/arm/kernel/hyp-stub.S: Assembler messages:
  arch/arm/kernel/hyp-stub.S:168: Error: selected processor does not support `ubfx r7,r7,#28,#4' in ARM mode
  arch/arm/kernel/hyp-stub.S:176: Error: selected processor does not support `isb' in ARM mode

Hi,

This can be seen with linux next-20160218 and arm e.g. allmodconfig.

Best regards,

V.
