Compile hyp-stub explicitly for arm v7-a.

Thanks for doing this. I just posted my fix to the patch system, before seeing yours (it also requires change in boot/compressed/Makefile - hyp-stub is built twice). See the previous discussion about this issue here: http://thread.gmane.org/gmane.linux.ports.arm.kernel/479256 Thanks, Jean-Philippe
